Arsenal midfielder Mathieu Flamini is adamant that Kim Kallstrom has the quality to prove his addition to the squad was worthwhile, as the Gunners bid to respond from a disastrous week in terms of their title chances.
Kallstrom finally made his Arsenal debut towards the end of Tuesday's 2-2 draw with Swansea City, replacing Tomas Rosicky with just 11 minutes left of the match.
Unfortunately for the Swedish international he failed to help Arsenal preserve a slender advantage at the Emirates, with Flamini knocking the ball into his own net just a few seconds before stoppage time as the Gunners conceded further ground on Chelsea, Manchester City and in-form Liverpool.
Arsene Wenger's men are desperate to prove their fleeting title hopes are still alive against City tomorrow evening, despite a number of key first-team stars being sidelined including Jack Wilshere, Aaron Ramsey, Theo Walcott and Mesut Ozil.
Flamini is relishing the chance to face City and prove critics wrong, insisting that a fully-fit Kallstrom provides a timely boost that can provide a much-needed boost heading into the business end of the campaign.
He told the club's official website: "I'm happy for him because it was his first game and we were all very happy to welcome him at Arsenal and in our team. It was a great performance when he came in.
"He's a player with a lot of quality and if he has some time to play I'm sure it will be very positive for our team."
"Of course it's been a difficult week, especially after the 6-0 at Chelsea and the draw but I think we have an interesting game tomorrow and it's good for us because we can prove to everyone that we can give a good reaction."
Wenger could choose to give the 31-year-old his full Arsenal bow against City, with the ex-Lyon star back from close to two months on the sidelines nursing a back injury.
Kallstrom will hope to prove he deserves to stay at the Emirates beyond the current campaign, with his short-term loan move to provide cover in central midfield expiring at the end of the season.
