Jack Ross is lining up his first signing as Sunderland boss - but could face some intense competition.
The Black Cats' boss is keen to land Ross County right-back Jason Naismith, who he has previously worked with at St Mirren.
Sunderland have reportedly submitted a £200,000 bid for the defender who was the standout performer in the Staggies' relegation from the Scottish Premier League last season.
But Ross' side will face some intense competition for the 23-year-old, with two more clubs said to have lodged bids for Naismith.

Aberdeen have made a cash-plus-player offer, and are hopeful of luring Naismith to Pittodrie with the promise of European football and the chance to compete for domestic honours.
Dons boss Derek McInnes - once a Sunderland managerial target - is known to be a big fan of the right-back and is keen to land him this summer.
Also interested are League One rivals Peterborough, who have confirmed that they have already lodged a bid.
Speaking to sister title the Peterborough Telegraph, Posh's Director of Football Barry Fry said: “We have made a bid for Naismith, but I have not been told it’s been accepted. If it has that’s good news and hopefully the player will come down to us.

“I spoke to their chairman and made an offer. He was due to get back to me when he returned from holiday. The player has also been on holiday so no transfer talks have yet been set.
