Arsenal boss Arsene Wenger insists Alexandre Lacazette substitution was not due to French striker's display after missing key chances at Chelsea

Arsenal boss Arsene Wenger insists he was pleased with the display of striker Alexandre Lacazette, despite taking him off in the 65th minute at Stamford Bridge.

Lacazette, who moved to the Emirates for £53million this summer, was guilty of spurning Arsenal's best chances as they drew 0-0 with Chelsea on Sunday.

The France international has only scored twice since moving from Lyon this summer, and was replaced midway through the second half by Alexis Sanchez in the second half.

Despite the change however, Wenger insists he was pleased with the forward's contribution. 

'I felt Lacazette had a very good first half. He worked very hard for the team, he's very disciplined and it takes him some time to maintain that intensity for 90 minutes,' he said.

'Don't forget as well I had Walcott, Giroud and Alexis on the bench, so after 65 minutes in a game of that intensity, it's normal that you bring some fresh legs in.

'I never ask any striker to understand that he has to make room for somebody else. You can never do that.' 

Arsenal picked up their first point at Chelsea in five visits to their London rivals, keeping their first clean sheet in 12 trips across the capital. 

Wenger's side are back in action on Wednesday evening when they host Doncaster Rovers in the Carabao Cup.
