Sunderland defender John O'Shea has hailed the progress of Republic of Ireland teammate Ciaran Clark.

O'Shea believes the influence of Aston Villa veteran Richard Dunne has rubbed off on Clark.

"He's been learning from Richie as well at club level. He's got a big, big future. He's really settled in and is growing in confidence.

"He's getting there as a talker, but that's what all the lads have to improve on - the communication factor. It just helps so much."
