According to a report in the Express, Rangers loan star Dominic Ball could be set for a return to Ibrox next season.
The proposed move appears to have gone down well among the Light Blues faithful, though it is only rumour at this stage.
However, with only Rob Kiernan and Danny Wilson signed up as centre-backs for next season, you would expect Mark Warburton to dabble in the defensive market this summer.
Here are three players he might wish to consider...
Reece Burke in action for West Ham
Due back at West Ham following a successful spell at Bradford City, in which he scooped SIX end-of-season awards and narrowly missed out on promotion the the Championship, Burke is likely to find the step up to the Premier League a sizeable one. Another temporary spell, either in the Championship or Scottish Premiership could help bridge the gap. Like Ball, the 19-year-old can also play right-back if required.
Warburton has already admitted to looking across the pond for talent and if he's been paying attention for longer than the past six months (when Mizaga moved to Chelsea) he's bound to have noticed the former New York Red Bulls centre-back. With John Terry having extended his stay at Stamford Bridge by a further year and new coach Antonio Conte expected to seek his own players this summer, the Blues could be open to a temporary move north for the 20-year-old.
One of Louis van Gaal's early Manchester United debutants, McNair failed to push on in his second full season at Old Trafford, though a ruptured liver suffered in October didn't help the 21-year-old's cause. With Jose Mourinho in the hotseat, many are fearing for the futures of United's young players and McNair, who can also operate in a variety of defensive and midfield roles, may wish to abandon ship in favour of regular games.
