As a half-time summary from my side;
Coleman is not on the pitch mentally.
Holgate needs to come off urgently, especially now when we are down to 10 men. So clumsy, inaccurate passes, out of position most of the time and his performance also affecting Keane.
Baines is average but looks so slow against the opponent's wingers.
Keane, I think he is average as well and as mentioned above, Holgate is pulling him down.
Gana is performing as always. Nothing special, nothing terrible.
Gylfi needs to involve a bit more.
Davies' movement and positioning are not bad but his passes are really terrible. He needs to improve his passes to help the team out on the pitch.
Richarlison was isolated and I think it was driving him mad, so he couldn't control his nerves. I still think it was a bit of harsh decision but still, stupid.
Cenk, trying hard but needs to try harder. Looks like Silva has given him a support role, hold the ball, deliver the ball, get in the box, off the ball runs etc. Silva looks satisfied with his overall performance so far as far as I see. Today, he can be a hero if he scores one. In my opinion, he is wasting his chances in the critical times.
