Alexandre Lacazette was happy to prove Arsenal's matchwinner for victory over West Ham.

The Frenchman would come on for Eddie Nketiah just before the hour mark and he'd prove to be the match winner as his 78th minute strike saw the Gunners close to within five points of fourth-placed Chelsea.

"I'm happy to score for the team," Lacazette said after the game. “We worked hard. It was a difficult game. I'm happy.

"It is my job to give the manager a big headache. I'm struggling to make the first team but I'm happy to score again today.

"I know that now I have to play well again the next game. Everyone wants to give their best and it's normal that whenever we do that we will perform as a team."
