Arsenal's inability to tie their stars down to long-term contracts could return to haunt them again this summer. Just under a year ago, with Samir Nasri entering the final year of his deal at the Emirates, the Gunners were finally forced to concede defeat and allow the star midfielder to leave for Manchester City.

The Arsenal hierarchy look set for another nervous few months this time around with a similar scenario affecting the futures of both Robin van Persie and Theo Walcott.

Discussions had been held before the Dutch striker headed off to Euro 2012, without any announcement on the outcome. Now, the Daily Mirror is reporting that Van Persie is set for more crunch talks with boss Arsene Wenger this week.

Juventus have tabled a rather inflammatory £8 million offer for the Premier League's Golden Boot winner, but according to the Mirror, they are prepared to go as high as £15 million. The likes of Paris Saint-Germain and Manchester City, who are also said to be interested, would likely be prepared to offer considerably more.

Though the club have suggested they would be prepared to hold onto the player for another year if he refuses to sign a contract, similar posturing was also made about Nasri last summer before they eventually relented.

Arsenal may be less troubled by the uncertainty over Theo Walcott's contract situation. The Mirror reports that the England international is looking to boost his wages by more than a third to £100,000 a week before agreeing a new deal.

But, with the winger still an inconsistent and frustrating presence, the Gunners could be ready to cash in if a substantial offer is forthcoming. Both Chelsea and Paris Saint-Germain are thought to be monitoring Walcott's situation, with an offer of £15 million said to be enough to tempt Arsenal into doing a deal.

One man that looks all-but certain to be departing the Emirates this summer is Nicklas Bendtner. The Dane enjoyed a mixed time on-loan at Sunderland last season; scoring eight goals but getting involved in numerous disciplinary problems that scuppered any chance of a permanent deal.

The perennially confident frontman put himself in the shop window with two goals at Euro 2012 and his agent Tom Brookes says the 24 year old will be on his way to a major side this summer.

Nicklas is a top striker, who just proved himself at the Euros, Brookes said, according to Sky Sports.

I'm certain that he is going to end up at a top club, but I'm not going to be drawn into speculation.

Reports in the player's homeland have linked him with moves to Malaga and Galatasaray.

Another striker who spent the last campaign on-loan, Joel Campbell, looks to continue his education away from the Emirates again next season. The Costa Rican joined the Arsenal last summer, but failed to attain a work permit and was subsequently sent out on loan to Ligue 1 side Lorient. Sky Sports now reports that after again failing to get the necessary paper work to play in the England, the 20 year old looks set to join La Liga outfit Real Betis.

It is a great opportunity for me to grow, Campbell told Fox TV.

I am going to the world's best league, and I want to play. I want to show what I am capable of.
