I've only really seen Lemar on YouTube but if you check out videos, he plays sort of the same position and does really similar stuff to Coutinho. He's just not as polished yet, not as good but Coutinho is I think 3 years older than him. What Lemar does have over Cout is pace too. He seems like he is like for like but I'm not gonna pretend im a Lemar expert.
Positives
Provides the set piece stuff we've lost from Cout's exit.
Gives the squad a point of difference, being a genuine left footed winger or central mid.
Agree that's he's quicker and more of a pass & move guy (as you alluded to in an earlier post).
Negatives
Doesn't have the rocket shot from distance and the super elite dribbling skillz of Cout (although not many in world football do).
Question mark re how he operates against parked buses, including his ability to pick a keyhole pass to unlock a packed defence
He is very slight and small in stature; not sure whether this is great considering Naby is a bit of midget as well
I'm pro-Lemar BTW, would take him at 60M euros.
