Looked comfortable in the middle tonight. Case for him playing there more often?
Yes. It looked very good with Mane in the middle. He looks like our fastest player to me. When he has time and space he sometimes misses basic things that a lot of players can do - a simple pass, for example; but when it's on instinct, there are few better. He can dribble and go left, right, head it, and do something completely unpredictable or spectacular. I'd keep him in the middle for the time being. Mo coming off the right is a good place for him.
I would play the same front three on Sunday. Even if Firmino passes a fitness test, stick him on the bench, as Everton fear Origi. Also, Firmino is a brilliant player and we will need a big game from him to get past Bayern Munich, for example; but his form has been a bit patchy lately, so I wouldn't be too worried about putting him on the bench so when he comes back he will be raring to go.
