Ter Stegen's move to Barcelona in doubt after transfer ban.Reuters

The agent of Borussia Monchengladbach goalkeeper Marc-Andre ter Stegen has put Arsenal on alert after revealing the goalkeeper's proposed move to Barcelona could be in doubt after the club was hit with a transfer ban.

The La Liga champions were sanctioned on Wednesday by a Fifa committee for registering and fielding 10 under 18 players and will now serve a 14 month transfer embargo.

The club have announced they will appeal the decision but their proposed move for ter Stegen has come under doubt as a result. The German shot stopper has one year left to run on his contract at Monchengladbach but his club confirmed earlier this year that he will be leaving this summer with a deal thought to be in place for him to move to Barcelona and fill the void soon to be left by Victor Valdes.

Reports of an agreement with Barcelona ended Arsenal's interest in the 21-year-old but should the Catalan giants be unable to conduct transfer business over the next two windows Arsene Wenger may be tempted to step in.

"We're very relaxed, but if I read Fifa's statement well, Marc for now can't join Barcelona this summer," ter Stegen's agent Gerd vom Bruch was quoted as saying by Bild. "The situation is unchanged, the goalkeeper will not be at Borussia next season."

Ter Stegen added: "I haven't heard anything about it and I don't know why you are asking me know," speaking to Kolner Express.

"I don't want to talk about it. I will definitely leaver Borussia Monchengladbach in (the) summer."

Arsene Wenger has been vocal in his support of current number one Wojciech Szczesny this season, but developments around ter Stegen's renewed availability could prompt him into action.

The club are also set to lose number two Lukasz Fabianksi at the end of his contract this summer while loanee Emiliano Viviano is almost certain to return to Palermo having not made a single appearance for the Gunners.

With Victor Valdes, who will miss the remainder of the season and the World Cup with a ligament injury, set to leave the Nou Camp at the end of his contract this summer, Barcelona could be presented with a huge problem finding his replacement if their transfer ban is upheld.
