London-based Premiership giants Arsenal and Chelsea are preparing to spend big on the German Bundesliga side Borussia Dortmund’s young Polish striker Robert Lewandowski and will try to lure the player away to the Emirates or Stamford Bridge, respectively, if latest reports are to be believed.

Gunners manager Arsene Wenger knows the importance of a second striker who can take the pressure off from Dutchman and skipper Robin van Persie.

The team has been more that dependent on van Persie throughout the season to deliver inside the six-yard box and although goals have come from every department of the team, a second striker is more than necessary, especially with out-of-form Marouane Chamakh possibly leaving at the end of the season and South Korean Park Chu-Young still not ready to play in the big league.

Chelsea, on the other hand, are also on the lookout for an able second striker who can deliver whenever needed. The blues are expected to lose veteran Ivorian striker Didier Drogba at the end of the current season, while Frenchman Nicolas Anelka has already left and Belgian youngster Romelu Lukaku still has a long way to go. Although Fernando Torres has found some form of late, he has remained silent in front of the goal for most of the season, which has had a major impact on Chelsea’s Premiership campaign.

Lewandowski, 23, can be an impressive buy for both the clubs, mostly because of his current form with Borussia where he has managed to bag more than 20 goals in all games. Although he has already signed a four-year contract deal with the club in 2010, it is to be seen if Borussia are ready to listen to any offers for the player.

Apart from Arsenal and Chelsea, Manchester City has also targeted the player, according to a Tribal Football report.

Lewandowski, who arrived at Borussia from Polish Ekstraklasa club Lech Poznan in 2010, has made as many as 86 appearances for the Westfalenstadion-based club and has also managed to score 34 times. He has also won 40 international caps for Poland and has bagged 13 goals.
