Wenger has said Giroud will not be leaving the club during the transfer window despite apparent interest from Everton and Marseille.
"We kept going and the spirit of the team was absolutely outstanding", Wenger said. "I know how important he is not only as a player but also in the group". "We were quite good previous year on corners and overall I believe that with a bit of work we can get that out of the system".

"We have a central midfielder and striker, so obviously another player would be one coming from the sides".
"We spoke and I saw last season how tough is this league. One was a corner, one on build-up, one on a corner again", he said.
