Arsenal striker Alexandre Lacazette is set to miss the next six weeks with a knee injury
Lacazette joined Arsenal last July from Lyon for a then club-record fee of £52.7million.
However, the France striker has struggled, scoring just nine goals in 29 appearances for the Gunners.
And after missing two glorious chances off the bench in Saturday’s north London derby defeat to Tottenham, he is set to sit out the next six weeks of action after undergoing minor knee surgery on Tuesday.
Arsenal signed another striker in January, with Pierre-Emerick Aubameyang arriving from Dortmund for £60m.
I kind of think Wenger brought him in because he didn’t get the top-level striker that he wanted
The Gabon international has started the last two Premier League games and Burley says Arsene Wenger initially wanted to sign a player of his calibre before getting Lacazette last summer.
“He’s been in the spotlight Lacazette, he comes in in the summer as a big signing,” Burley told ESPN FC.
“I don’t want to be harsh on him, I don’t want to be harsh on any player, but I kind of think Wenger brought him in because he didn’t get the top-level striker that he wanted.
“So he went down to the next level and brought in a very good player from France.
Craig Burley does not think Alexandre Lacazette was Arsene Wenger’s first-choice signing last summer
“He’s left him out of some key games, which was strange, or maybe told a story.
“Then obviously the chase for Aubameyang and securing Aubameyang was going to shove Lacazette onto the sidelines.
“We saw him come off the bench in the north London derby, missed a couple of chances, it happens, confidence is low and off the back of that now he is injured.”
