Palace were once again competitive and resolute in their defending against an in-form opponent at Selhurst Park, but suffered a 1-0 loss after a foul on Ilkay Gundogan inside the box late on allowed Erling Haaland to convert the resulting penalty.
Vieira said: “It’s happened too many times when I’ve mentioned we should have got something from the game. I’m really frustrated because we defended well against City. We needed to defend well, and I think we did.
“The frustration is about conceding the penalty: this is something we should avoid, and the lack of concentration in that moment gave away the hard work from the players on the field today.
“We needed to make it tough because we know how good they are. We were well-disciplined, we were aggressive, we tried to kill those spaces they like to use, and I think we did it really well.
“But that moment from the corner, where there was a lack of attention and organisation… I expect the players, in those moments, to take more leadership, for somebody to have more voice and organise [us] to defend better.”
