Arsenal appear at risk of losing goalkeeper Lukasz Fabianski on a free transfer this summer, with the goalkeeper's contract set to expire.
The Pole had an awful start to his Arsenal career after a number of high profile blunders which condemned him to becoming a back-up at the club.
Over the past two seasons however he has bounced back to become Mr Dependable, impressing whenever called upon by Arsene Wenger, even called up to displace Wojciech Szczesny at the end of last season, before relinquishing his place through injury.
Just last month he stepped up when his compatriot was suspended, saving a penalty in a creditable 1-1 draw away to Bayern Munich, even if this could not stop the Gunners exiting the Champions League.
His performance is said to have impressed another high profile German side - last year's Champions League finalists Borussia Dortmund.
Italian website Tuttomercatoweb report that Dortmund have enquired after Fabianski, joining Schalke and Basel in pursuit of the 28-year-old.
Fabianski has made eight appearances for Arsenal this season in all competitions, conceding eight goals.
The club may face a tough ask in trying to convince the player to stay, knowing he is second choice, but the calibre of sides interested in his services illustrates just why they should take a second look at it.
He has proved a more than able deputy to Szczesny, and in the view of some, is deserving of a run in the side.
Allowing him to leave will mean Arsenal must use their resources to identify and recruit a new back-up this summer, with on loan Emiliano Viviano almost certain not to sign a deal.
