I thought he wasn't bad at all yesterday. It is apparent that he's way better offensively than defensively. That cross to Son though was amazing. His delivery is one of his greatest strengths. As
@El Guepardo said, give him some time. That was his second appearance for us after coming in mid-season. Not all players can just slot in like Bentancur and Kulu did, and maybe it's because they have a background playing in Seria A that they're so comfortable in Conte's system.
Overall, I think it was something to build on but for sure he needs to do better. Then again, so do half the team. Son and Richarlison were just smashing the ball into players or not connecting passes, PEH headed the ball and almost got an assist for Coulibaly, our whole back three was at best average... all fans need to have some perspective.
