I doubt on that lad for his physicality. He looks like he weighs 8 stone wet through.
But regardless, I can't see how that substitution could have helped us. He looked absolutely lost.
Agree on KM, he's a bit of a bell but he does like to get on the ball. It would have been nice to get KM on to try and bridge the gap between the ever deepening midfield and Lukaku.
I don't blame the kid for looking totally out of his depth. It's the merseyside derby for christ sake.
I'm being a bit dave here I know BUT I think it was a bit of an eff off from Koeman to the fans and media.
"You wanted me to play the kids, I said they weren't ready. And now i've proven it."
I just cannot see how that was ever going to end well bringing him on.
