He said: "I can't help thinking that Aubameyang coming in, there's no way him and Lacazette can form a partnership, I just don't see that at all. They both look like penalty box strikers.
"I think Aubameyang's goals for Dortmund, only one was outside the box. That's not a problem, but it shows he's a penalty box centre-forward, he's exactly like Lacazette.
"I could actually see Lacazette moving on at the end of the season, but big signings. Going forward for Arsenal, you still worry that the problems at the other end of the pitch have still not been rectified."
