Middlesbrough boss Gareth Southgate has told Sunderland it will take £10 million for them to re-sign Julio Arca.

Southgate admitted: "I didn't find it strange they wanted him back, the way he's been playing.

"But he is one of our most important players - £2m has been mentioned but it would take about five times that now.

"He's a class act and is very happy here. He has ability on the ball, keeps possession but also works his socks off and puts his foot in."
