Depends what you class as a mistake.
Last night's mistakes (off the top of my head without watching back).
- hesitated after Vini's poor touch and then took him out, saved by the offside.
- off balance for Mbappe's shinner, better balance and it was an easy catch, or at worst, a diving save.
- praised for a one v one save against Vinicius, but I feel the low cross was one he should have come for in the first place.
- horrendous dropkick straight to Real.
- aimless parry straight to Brahim.
- walkabout for no reason on the 3rd goal.
It's not good enough for a team wanting to win things. Neither keeper is in great form, both possibly don't want to be here any more. We need 2 new ones in the summer. Regardless of all the other mistakes by other players, if the keepers were on opposite sides last night we'd have had a comfortable win.
