The Pole is reportedly a target for Manchester United, Arsenal and Chelsea this summer but the striker's representative has told competing clubs to up their bids

Leading Premier League clubs have been warned by the player's agent that it will take a money-spinning offer to tempt Borussia Dortmund into selling Robert Lewandowski, Goal.com has learned.
The striker's representative Maik Barthel has confirmed that offers have been received from some of England’s top flight sides but insisted that, with interest continuously growing, clubs will need to up their bids in order to land the forward.

"Unofficially there are offers from English top clubs." Barthel told Goal.com. "We respect the contract situation in Dortmund and don't want to take part in speculation. A £13 million transfer fee is not suitable."
The 23-year-old has been strongly linked with a move to Manchester United this summer, where a deal would see him link up with former team-mate Shinji Kagawa, who joined the Red Devils from Dortmund in June.
However, Sir Alex Ferguson has recently confirmed the club's interest in Arsenal's wantaway striker Robin van Persie, who revealed his desire to leave the club in an open statement to fans, possibly instead paving the way for the Gunners to bid for the Polish forward.
Reports on Saturday morning also suggested that last year's Champions League winners, Chelsea, have joined the race to secure Lewandowski's signature, but that they had an offer of around £13m turned down.
The Blues are thought to be looking to replace Didier Drogba after his departure to Chinese club Shanghai Shenua and turned to the Pole after Napoli's Edinson Cavani proved an unviable option.
Lewandowski scored 22 times in 34 games in the Bundesliga last season, adding seven goals from six appearances in the German Cup, including a hat-trick in the final as Dortmund crushed Bayern Munich 5-2.
