Arsenal striker Olivier Giroud has claimed that he has returned to form after struggling against Monaco three weeks ago.

The Frenchman missed a number of chances to score and now the Gunners face a big task of qualifying for the quarter-finals of the Champions League due to the 3-1 defeat from the last-16 first leg.

On Saturday, Giroud was much improved as he scored the opening goal and played a part in the next two as Arsenal sealed a 3-0 win over West Ham United on home turf.

"There are always tough moments like that because we do a hard job," The Express quotes Giroud as saying. "If you let the doubts enter your head it's even more difficult to cope.

"You have to question yourself every week and bounce back. I try to show my answer on the pitch with my mentality. It was nice to do it against West Ham."

The North London outfit will face Monaco for the second leg in France on Tuesday.
