Olivier Giroud says Arsenal manager Arsene Wenger has helped the France international improve his finishing.

The 27-year-old scored the opening goal in les Bleus’s 5-2 victory over Switzerland in their second Group E game at the World Cup on Friday.

Arsene Wenger often gives me corrections after matches. We are talking about opportunities Olivier Giroud

Giroud finished the Premier League season with a respectable 16 strikes – but the former Montpellier man knows he can improve further.

“I feel I can go on improving,” Giroud told L’Equipe. “I can improve some parts of my game and have better statistics.

“I have to be more decisive in the box, but also in my way to keep the ball and defend. You have to be demanding, trying to find peace in front of goal. At least once a week I try to work in front of goal. I have been doing it systematically since I have been at Arsenal. I need it.

“Arsene Wenger often gives me corrections after matches. We are talking about opportunities. To him, I am not crafty enough. Once he told me I am too frank in my runs, too predictable. I have to be more confusing.”

Giroud has scored 27 goals in 70 Premier League appearances since making a £10.6m move to north London in 2012.
