Newcastle United captain Jamaal Lascelles admits there was a lot of anger over the manner of defeat to Watford.
Lascelles admits their untimely errors cost them dearly during the 2-1 loss at Watford.
He said: "The whole of the first half we controlled the game.
"Defensively we looked fine, we knew they'd be dangerous from set-pieces but we saw the first half out and obviously we were a goal up.
"The second half, credit to them they came out with a bit more fight, but even still even in open play I don't think they caused us many problems.
"It was just two errors we're not happy with and it's cost us the game."
Asked about the prospect of bouncing back, Lascelles added: "It was a lack of concentration that cost us.
"Every game we play we want to win.
"To be honest I thought we'd bounced back from Man City but mistakes cost us and we just have to get it right for the next game."
