Sunderland midfielder Jack Colback was left frustrated by their 0-0 draw at Aston Villa.

Colback believes Sunderland, who had a goal chalked off for offside late in the second half, should have taken more from the game.

"It was frustrating to only come away with a point, especially after last week's goalless draw," Colback told safc.com.

"We just couldn't get that breakthrough we needed.

"It was a very frustrating afternoon and it's a game that we felt we should have won.

"It was an open game all round, but we looked dangerous on the counter-attack and could have scored maybe three or four goals."
