Alexandre Lacazette expressed his delight at scoring for Arsenal on Saturday afternoon and hopes to continue giving Mikel Arteta some selection headaches.

The Gunners secured a narrow win over West Ham United to boost their hopes of finishing in the Premier League top four.

The Frenchman's 78th minute strike at the Emirates stadium moved the Gunners up to ninth spot, five points behind fourth-placed Chelsea, and the striker said he will continue to 'fight hard' to make Mikel Arteta's starting XI.

West Ham, who had better goalscoring chances in the match at north London, remain 16th, above the bottom three only on goal difference.

Former Argentina goalkeeper Gatti has taken aim at Messi.

"I’m happy to score for the team," the 28-year-old said after the victory. "We worked hard. It was a difficult game. I’m happy. They deserved more because of the chances they created. This is football, sometimes you don’t get what you deserve.

"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."

Lacazette has now netted nine times in 26 league matches this season.
