Sunderland are holding talks over a loan move for Callum Doyle, as per the latest news from Roker Report.

The Manchester City youngster enjoys a glowing reputation after coming through the youth ranks of the Premier League champions and making a number of appearances at under-18 and under-23 level which led to the club winning the Premier League 2 title.

As a result the 17-year-old is seeking regular first team football with a move to Wearside potentially on the cards.

It's claimed that Sunderland are eyeing a two-year loan deal for the central defender which will allow him the opportunity to really settle into his surroundings and immerse himself into life at the Stadium Of Light.

But what are the potential knock-on effects that Lee Johnson will need to be aware of if a deal goes through? We take a look.

The end of Dion Sanderson pursuit?

A move for Callum Doyle could be bad news in the club's pursuit of Dion Sanderson.

Sunderland are interested in making a move for the central defender after a thoroughly impressive campaign on loan at the Stadium Of Light last season.

However with Sheffield United now among the clubs chasing his signature, perhaps this is a sign that Sunderland's hopes of striking a fresh deal are all-but over.

Plenty of options for Lee Johnson to consider

Signing another central defender was always going to be a priority so that Sunderland were well-stocked in that area.

If Callum Doyle does join then it means that Johnson will have Bailey Wright, Tom Flanagan, Jordan Willis, Arbenit Xhemajli and even Luke O'Nien who can play in defence, and if Doyle joins there will be one more for that list.

Given the selection and injury problems that the Wearsiders had last term the focus will surely be on making sure that they have more than enough options in a troubled position.
