Koscielny up for the Cup
Arsenal defender Laurent Koscielny admits that the domestic cup carries far more weight in England than it does in his native France.
Ahead of the Gunners' FA Cup fourth round clash at home to Aston Villa, the 26-year-old is fully aware of how important the competition remains to the club's fans, and insists the players will be doing everything they can to ensure progression to the next round.
"In France we have the French cup," Koscielny told Arsenal.com. "But I don't think we have the same atmosphere as the FA Cup.
"Here it is an important trophy but in France it is less so. I know in England that winning the FA Cup is a very big trophy for the team."
Koscielny is expecting a tough test when Villa arrive at the Emirates Stadium on Sunday, after coming through a tight encounter in the reverse fixture in the Barclays Premier League at Villa Park.
"You know that the FA Cup is difficult because it is a hard game for 90 minutes," he added. "We know Aston Villa, we won away but it was a difficult game.
"Now it is at home we want to go as far as possible in this competition and so we have to win this game.
"It is important for the team because we have lost our last three games, and for the supporters because they were not happy after those defeats."
