Arsenal goalkeeper Lukasz Fabianski will miss the rest of the season as he requires surgery on a damaged shoulder.
The Pole broke down with the problem during the warm-up ahead of Arsenal's Barclays Premier League match against Manchester City last month and has not played since.
Boss Arsene Wenger confirmed this morning the 25-year-old - who had established himself as Arsenal's first-choice goalkeeper - will head to Germany for surgery.
Wenger explained at a press conference this morning: "We had bad news for Lukasz Fabianski because he need surgery on his shoulder.
"He has decided after having seen a few specialists that he will have surgery in Germany. It means his season is over."
Manuel Almunia has just returned from an injury lay-off and will now battle with youngster Wojciech Szczesny for the number one jersey.
Wenger continued: "The competition for the places at the moment will be between Wojciech and Almunia. Wojciech will play the next game."
