And that having Kolasinac and Lacazette will offer more defensively than anyone else in those positions, which would be wise for Emery to think about considering the league we play in and the way in which we play in it.
The real issue would be that the two are one dimensional going forward, compared to say Ceballos/Ozil and Pepe(debatable)/Saka. Which I don't think is the case, but even if it was - are we all that multidimensional of an attacking team, anyway? With Auba upfront, I don't even think we need to be. I don't see the two boys fucking up too many counter attacks, and when the other team gets bodies behind the ball, or parks the bus, we tend to get it to the wing and hope to open up space from there, anyway.
Lacazette is a weird one on this forum as opinions are split more on him than probably anyone else on. And though concerns over his creativity, and ability to dictate the tempo and rhythm of our attacks may end up being valid, who right now is guaranteed to offer more?
