Arsenal and Manchester United have been put on alert after Robert Lewandowski again fuelled speculation about his future by reiterating his desire to play in the Premier League.
Lewandowski's agent recently confirmed United's interest in his client, while reports earlier this month suggested Arsenal were also keen on the Borussia Dortmund striker as they look at possible replacements for Robin van Persie, who has confirmed he has no plans to sign a new contract at Emirates Stadium.
Chelsea and Tottenham are also understood to have shown interest in the 23-year-old, who has two years left on his existing deal with Dortmund and recently said he believed it would be hard to accomplish anything else with the Bundesliga club.
Speaking to Bild, the Poland international said of the Premiership: "This is a league in which I would like to play and I hope to manage that at some point."
Dortmund insist Lewandowski is not for sale, however, and claim he could agree to a contract extension.
"The reality is Borussia Dortmund, this is just a dream," said Dortmund sports director Michael Zorc.
"There is nothing wrong with someone dreaming of the Premier League. We are experts in handling this."
And of the possibility of fresh terms being agreed, Zorc added: "We remain in constructive talks.".
Prior to Euro 2012, Poland coach Franciszek Smuda had claimed Lewandowski was likely to be playing alongside former Dortmund midfielder Shinji Kagawa at Old Trafford next season, as well as stating that the Bundesliga outfit were also likely lose Lukasz Piszczek and Kuba Blaszczykowski.
"In my opinion, in a moment they will be gone from Borussia," Smuda had told reporters.
"'Lewy' is going to Manchester United, Kuba also somewhere in England, Piszczek to Real [Madrid]."
