I won't hold this one against Cancelo, but I felt he was the wrong player for tonight.
Cancelo is like De Bruyne in that he plays a high risk sort of game. I think tonight Cancelo's style of play was always going to cause us problems, just by how many risks he takes. Also being a right footer I think he forced us into playing narrower than we should have done.
He still had some really good moments, in attack and defence. But a few scary moments too.
I think had the game gone entirely like the 2nd half did he could have shined like he did against Tottenham, but it didn't, so he didn't.
Hopefully he noticed whatever Walker did when he lost his place, and now makes the effort to return the favour.
