Wednesday's 2-1 victory in the Carling Cup was goalkeeper Fabianski's first of the season after recovering from knee surgery. He played the entire match and later spoke of his delight to be back in the side.

But since then, manager Arsene Wenger has revealed his young keeper is set to miss the Gunners' upcoming matches.

Speaking of the latest setback for the Polish goalkeeper, Wenger told the club's official website: "We lost Lukasz Fabianski with a thigh injury. He will be out for three weeks. Of course, it is big disappointment - because he has just come back from injury."

In Fabianski's absence, Wenger will choose between Vito Mannone and Manuel Almunia when he selects his goalkeeper for Saturday's north London derby against Tottenham Hotspur.

Wenger has also ruled Jack Wilshere (ankle), Theo Walcott (knee), Denilson (back) and Tomas Rosicky (knee) out of his plans for the Emirates Stadium encounter.
