It's like the Leicester game didn't exist.
He's gone from dominating a game in which he hit the bar twice and was denied at the very least two assists from poor finishing to "not good enough" in 90 mins against the reigning champions whom we have a catastrophic record against away from home.
He's not suited to games where we don't have the majority of possession. When we dominate the ball, as we did against Leicester, he looks excellent.
Horses for courses possibly.
Ironically, in the games where we struggle to hold onto the ball Man C, Arsenal, Brighton for example, Coutinho has looked excellent. So play him in those games and Buendia in the others?
