A former Manchester United defender - who was part of the side that lifted the Europa League in 2016-17 - is in talks to join Real Betis.
The free agent has been talking to Sheffield United and Luton Town this summer as he looked to secure a deal with a Premier League side.
Both the Blades and Premier League debutants Luton have struggled on their promotion to the top-flight this term, with both shipping a combined 16 goals so far this season.
As such, they may be keen to shore up any holes in their thus-far leaky defences that may have arisen, with free agents the best source of reinforcement now that the transfer deadline has passed.
