Crystal Palace boss Patrick Vieira admitted frustration after their 0-0 draw at Leicester City.
Vieira admits they were poor for today's clash.
He said, "In the first half we had a situation that allowed us to create more and I don't think we were aggressive enough going forward.
"In the second half it was all about them, we didn't create anything, but on the flip side we defended well and kept a clean sheet. Of course there is frustration, but we will take a point today.
"We had a poor second half I would say, we were flat and didn't hurt them. We were not brave enough to break the lines.
"We didn't take much risk and this is whey we did not create very much, especially in the second half. We have to perform better."
