Alexandre Lacazette was replaced by Alex Iwobi with 12 minutes remaining against the Claret on Saturday, with the Nigeria international going on to score the clinching goal in a 3-1 success for the Gunners.
However, speaking in his press-conference Unai Emery claimed that he is happy with Lacazette’s reaction as players should be angry if they are taken off.
The Arsenal striker had the look of someone who desperately wanted to make a mark all afternoon and reacted furiously when he was removed from the action.
He appeared to get into a heated debate with a member of Arsenal’s coaching staff before taking his seat in a huff.
“I think he was happy with our victory,” said Arsenal’s head coach.
“He wants to score and when a striker doesn’t score, I like it if he is angry with this situation.
Arsenal legend Ian Wright came out in support of Lacazette after the game, with the club’s second record scorer taking to social media back the France international.
“Laca obviously disappointed,” Wright tweeted. “As a striker you know when there are still goals out there – game is stretched and he wants to score.”
