Rovers have reportedly made an “official approach” for Sunderland defender Danny Batth.

The 32-year-old emerged as a target earlier this summer as Jon Dahl Tomasson aims to add experience to his young squad following the departures of Daniel Ayala and Thomas Kaminski among others.

Batth was named Sunderland’s Player of the Year last season, making 40 appearances in all competitions.

He also played a key role in the Black Cats’ promotion from League One under Alex Neil the previous campaign.

The centre-back is entering the final year of his current deal at the Stadium of Light and could be on the move before the transfer window slams shut in less than two weeks’ time.

Queens Park Rangers are also said to be interested in Batth, who is yet to feature in the league this season.

Batth is one of several experienced players at Sunderland who could be on the move, and Tony Mowbray has already hinted he won’t stand in their way if they want a fresh challenge.

"I've been in football a long time and I understand how squads need a balance of experienced players, and I do think it's different for all of them really,” Mowbray told The Sunderland Echo.

"Some of it might be about how much of your budget you're going to commit to someone who might not be playing.

“Players have outlays - cars, mortgages etc - and when you get to the last year of your contract, you start wanting to negotiate a new one.”

He added: “I'm only really interested in what happens on the grass. When we're playing Luton away, I would prefer Danny Batth right in the middle there, heading the ball out of the box.

“But if you get to an impasse where there isn't a new contract offer that's suitable, and we're seeing what else out there. As I've said, if there is no sale when the window shuts then they are here and part of it.

“At this moment, I am just respectful of the players. I like them all and they did exceptionally well for the club last year in different roles.”
