When you try to deny the obvious you succumb to semantics and corny ass jokes lol. He made that assist by using one of his strengths aka pressure and win the ball high against a carefree and sloppy Bayern defense (Neuers fault mostly), how is that an indication of him being good/ideal for counters? He is a target player, he can try to bulldoze his way through defences on some counters but usually he is NOT remotely good at it, he is more adept of playing lay offs or heading/receiving long balls. He is pretty much lacking when he has to run into space with speed with or without the ball, and doesnt the technicality to dribble his way out of trouble in such quick counters either.
He generally been little more useful team player/well rounded then Morata, but if there is a HUGE drawback for us in using him instead of Morata in CL then that is 100% the counters. Alvaro litterally kills at such a scenario while Mandzu is just barely average at it. On that aspect alone it is an issue and CLEAR drawback to downsize our strength in it(especially more so when we arent the ball dominating type of team in big games, need all the advantage we can get on counters). Even Zaza is better at this despite his awful first touch.
