The French striker scored the opening goal of the weekend in the Premier League, latching onto Dani Ceballos’ corner in the 13th minute and firing through a crowd of bodies past Nick Pope.
Ashley Barnes levelled for the visitors just before half-time before Pierre-Emerick Aubameyang secured three points for the Gunners in the 64th minute, finding the net from the edge of the box after Ceballos won the ball in midfield.
Dyche was delighted with Burnley’s ‘mentality’ but blasted Arsenal’s tactics, accusing Unai Emery’s men of playacting to win free-kicks throughout the 90 minutes.
He said: ‘It’s grown to a level where it’s not a silly thing. It’s every week now. You know on Match of the Day they used to highlight it… going back seven or eight years they used to highlight it – now they don’t even show it!
‘It doesn’t even get shown now. That’s peculiar about life. Probably about life actually. Yeah, probably is about life.
‘You know when you’ve got kids and they do a maths test and the teacher says your kid cheated. “Well done, that’s alright. Well done!” – do you do that?! I don’t think so. You go: “What are you doing?!” and you agree with the teacher or you should be agreeing with the teacher.
‘It’s unacceptable, this is professional sport. Acceptable to just get a yellow card to cheat. Literally.’
Lacazette clearly saw the funny side after the match and responded to a clip of Dyche’s rant on Instagram.
After ‘liking’ the post by ‘threesixtytv_’, Lacazette replied with three crying laughing emojis in the comments section.
Lacazette assured Emery that the best was yet to come from him in an Arsenal shirt following the victory.
‘The Premier League has seen a very good Lacazette, but not yet the best Lacazette,’ he told Canal Plus.
‘I need to score more goals I know, I need to be more consistent and consistent throughout matches. I can do better.’
Loan signing Ceballos was named man of the match against Burnley and Emery praised the Spaniard’s performance.
On Ceballos and David Luiz’s first starts at the Emirates, Emery said: ‘Yes, [they were] very good. [It was] their first match here at home officially.
‘I want to speak about the team. But individually [they were] also good. [Nicolas] Pepe good, Dani good, David Luiz good, and other players also.
‘I think continuing with Laca scoring and Aubameyang scoring is good. The only thing we didn’t do today was keep a clean sheet, but we will.’
