Months after newcomer Sergio Agüero slammed in the 94th minute winner against QPR and won Manchester City their first ever title, he'll have to do it all over again. Yet this season, it won't be a simple two-horse race. With more teams strengthening their side, this year's Premier League title can be won by just about anyone.

With fans eager to see their club succeed, it is up to new signings to make the biggest impact and justify their transfers. No bigger than this season's most expensive player who signed for £32m.

Eden Hazard - Chelsea

Coming to the Premier League can be tough but when you're one of the biggest protégés in the world and the club you're in has just won the Champions League, things seem a little easier. It is 21-year-old Eden Hazard who so overwhelming set the world alight by scoring 20 goals and creating 15 assists as his side finished third in the league. Hazard was joint top scorer to Montpellier's  Oliver Giroud even though he played primarily in midfield.

Such is the Belgian's ability that he started Chelsea's first game in incredible fashion. Just two minutes in, the wing-wizard earned the Blues a penalty before setting up Branislav Ivanovic for their second. Three days later and he was at it again. Against Reading this time, the 5ft 7in midfielder won another penalty and assisted a further two goals to give Chelsea two wins out of two.

What is so admirable about Hazard is the fact that he is a very unselfish player. If you see Chelsea's fourth and final goal against Reading, the youngster could have smashed the ball into the empty net but he chose to square for Ivanovic as he was dead certain to score. At just 21, this kid has incredible potential and Chelsea may just have unleashed a future World Footballer of the Year.

Santi Cazorla - Arsenal

Arsenal began their season just as they did in the previous - by playing out a 0-0 draw. However, it was new-signing Santi Cazorla who completely stole the show as his creativity was reminiscent of a certain Cesc Fàbregas; a player the Gunners have been desperately looking to replace.

Cazorla came to the club at the beginning of the month and it was the 27-year-old who dominated possession and  seemed to be at ease from the very beginning. Although he couldn't help Arsenal find the necessary finish, it was his imaginative reverse pass which opened a tight Sunderland defence to unleash Oliver Giroud on goal. Had the finish been better, Cazorla would have been praised for an imaginative assist but it wasn't meant to be.

Arsène Wenger has already likened him to the great Robert Pires; a midfielder whose sheer class was too much for the opposition to handle in the era of 2002-2005. A winger at heart with the technicality for performing in the centre of the park, at just £16m in this day and age, Cazorla looks a steal.

Lukas Podolski & Oliver Giroud - Arsenal

With 70% of the possession, the Gunners dominated proceedings and created chance after chance although they just couldn't find the finish. Lukas Podolski was quiet on his debut and couldn't get into the game. It was his transformation from playing on the left of an attacking trio to the centre-forward role that may have hampered his performance but the German is usually a lot more clinical than what he showed against Sunderland. Needing time to settle in, the 26-year-old striker may have preferred to remain in midfield but with Wenger's background, he will probably convert to a top-quality forward.

His replacement in the match Oliver Giroud looked impressive in holding up the ball as he used his size and strength to his advantage - something Arsenal haven't managed to excel in. He didn't get as many opportunities to shoot as he would have liked but when an 83rd minute chance fell to his feet, his right-footed effort skidded wide. It is something Giroud will have to work on if he is to emulate his form last year in Ligue 1. Both him and Podolski are strongly left-footed and both must be able to hit them on their right just as well if they are to succeed.

Fans must have been rightfully enraged at Robin Van Persie's departure to rivals Manchester United but how they would have loved for him to have been at the end of that opportunity.

Robin van Persie - Manchester United

Talking about the Dutchman, Van Persie was given 25 minutes to shine on a night at Goodison Park; arguably one of the toughest away stadiums to play in. Having already shown the world just how prolific he can be when fit, the former Arsenal star was surprisingly benched for the fixture against Everton.

Having the top-scorer of the Premier League last year and the runner-up side-by-side is a mouth-watering prospect. Sir Alex Ferguson has not only strengthened his side considerably from last season but has also weakened rivals Arsenal. There is no doubt Van Persie has the quality to become a huge success and a trophy will not be too far away for the 29-year-old.

But when push came to shove, neither him nor Rooney could penetrate a stubborn Everton defence. With David Moyes excellently presenting tactics which urged his players to close down early and hit balls to Marouane Fellaini in the air early, United were left licking their wounds. Crosses and passes from Van Persie were not as telepathic with his team-mates as they were at the Emirates but bearing in mind this was his very first game, it won't be long until he finds the net on a consistent basis.

Michu - Swansea

One player who wasn't prone to chances was Swansea's £2m signing Michu. The Spanish midfielder absolutely stole the show on his debut for the Swans by bagging a brace at the Liberty Stadium. Manager Michael Laudrup seems to have found the bargain of the summer in the former Rayo Vallecano star.

The Welsh side controlled the game from start to finish but didn't get going until Michu fashioned a shot from 25 yards to give Swansea the lead. After the break, he struck again by bending in an absolute pearl of a goal to make it 2-0. It was a fantastic finish and something Swansea will need to mount a serious challenge for Europe this season. On the basis of his performance, Michu will be vital this campaign and you wouldn't bet against him scoring more wonder goals.

A 5-0 win for Swansea is the perfect start and shows you don't have to spend big to produce a star. Can he prove to be the signing of the summer?

Mladen Petric - Fulham

Well this guy gives him a run for his money. And why? Because he cost absolutely nothing, scored twice and set up another to help his team to a 5-0 win. The experienced Croatian is just that good.

As if a winning start isn't enough, Martin Jol led his side to a stunning five goal victory over last season's strugglers Norwich City. Arriving from Hamburg, it was the 31-year-old who made it 2-0 as he buried a powerful header from a corner. His second goal came with a stroke of luck as it took a deflection to beat John Ruddy but it was Petric's willingness to shoot which provided the goal. But nothing compared to the beauty of Fulham's fourth goal.

Having a quick ball played to his feet, the Croat's inspiring back-heel found Alexander Kačaniklić who made no mistake and sweetly stroked the ball into the net. Norwich had a day to forget as their defence simply couldn't cope with the strength and skill of the Fulham frontman and with this being a free transfer, Martin Jol may have made the coup of his life.

Of course this is just the beginning of the season and with thirty-six games to go, anything can happen. More signings could be made before the end of the transfer window too but for now, these debutants have done their club proud. The question is, can they continue to impress?
