Alfie Burns It looks a fairly solid deal for Sunderland. Tanser is a player that, at 26, is just coming into his best years. If he’s giving them to Sunderland, it’s not a bad thing at all. My opinion on Sunderland this window is that they have to give Lee Johnson what he wants. They’ve appointed a manager that’s of a really high calibre, but he needs backing properly. If he believes Tanser improves his chances of delivering play-off football, Sunderland have to get him through the door. That’s the top and bottom of it.

Quiz: Have any of these 22 players ever been in Sunderland’s academy?

Jacob Potter He could be worth the punt for Sunderland. Tanser has been an excellent servant to St Johnstone over the years, and I think he could be a solid addition to Lee Johnson's team this season. Competition for places is never a bad dilemma to have as a manager, and Tanser would be quietly confident that he could force his way into the Black Cats' starting XI this term, as they target promotion. But Sunderland will know that they face a real battle to land his signature, with Championship side Barnsley also keen on a deal for Tanser. It's set to be an interesting few weeks on this potential deal, and I think it would be a shrewd bit of business by Sunderland if they secured his signature. George Harbey I’d say it'd be an important addition. Denver Hume has had a couple of injury issues of late, and Dion Sanderson is a natural right-back who is having to play on the left. Tanser is at a good age, he has a lot of experience under his belt and he is in his prime, and his contract situation means they could get him for a bargain. He has been a key player for St Johnstone this season, and he’d probably jump at the chance to join a massive club like Sunderland. He’d play regularly, you’d imagine, so it addresses an area of the pitch which lacks depth.
