That gives you the opportunity to do things you're not used to, and that's what helped him.
Things got worse for City when Sadio Mane made it 3-0 to the Anfield outfit.
'He's an outstanding talent still, still a lot of things to improve, no problem with that'.
"That's all good [but] all players can improve and that's where he can improve of course as well".
