Sunderland boss David Moyes is pleased with the progress of Patrick van Aanholt.

Moyes says the Sunderland coaching staff are on the left-back's case “big time" in training when it comes to working on the defensive side of his game.

“I have seen bits of improvement," Moyes told the Sunderland Echo.

“We have had to dig him out at times and we are on his case big time.

“Against Liverpool we saw an awful lot of things we didn't like.

“He has great ability going forward and we want him to keep doing that, we want our full backs to be attacking, we want them to join in and give us width at times.

“But their first job is to make sure they are good defenders and they stop crosses and to make sure they are at the back post to defend balls in from the opposite side of the pitch.

“So, he needs telling regularly and we keep on at him.

“But he has been better in recent games, he has steadied a bit."
