Transfer interest is building around Jon Mikel Aramburu Mejias, with Liverpool understood to be weighing-up a move for the Real Sociedad defender. While there has been no official bid as yet, the club may act swiftly if they decide to pursue the deal before the transfer window slams shut. Liverpool remain optimistic, but the deal is not without hurdles. Manchester City and Manchester United continue to monitor developments and could yet re-enter the race if negotiations stall or valuation gaps remain unresolved. With only 4 goals conceded in 4 (1.0 per game), Liverpool have been one of the stronger defences in the Premier League this season.. Jon Mikel Aramburu Mejias would be asked to keep that standard and provide dependable cover when needed. Speculation continues to connect Liverpool with Tyrick Mitchell, Estevao and Aleksandar Stankovic while no fresh rumours surround Real Sociedad. More on this story as it develops.
