Greece winger Charis Mavrias is set to become Paolo Di Canio’s 10th summer signing.

And that is likely to spell the end of James McClean’s turbulent spell at Sunderland with Celtic closing in on the £2million-rated Republic of Ireland star.

Mavrias 19 is set to arrive on Wearside in the next 24 hours to complete a medical and finalise terms on an incentive-based £1.25m move from Panathinaikos which could rise to double that amount.

After the £6m arrival of Italy midfield ace Emanuele Giaccherini from Juventus earlier this month McClean is down the pecking order.

Sunderland will make a healthy profit on McClean snapped up from Derry for a bargain £350000 two years ago.
