Transfer interest is building around Oscar Mingueza, with Leipzig understood to be weighing-up a move for the Celta Vigo 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. Until a fee and conditions are finalised, the deal remains vulnerable to disruption - especially if Marseille, Aston Villa and Newcastle decide to make a formal offer of their own in the coming days. With only 13 goals conceded in 10 (1.3 per game), Leipzig have been one of the stronger defences in the Bundesliga this season.. Oscar Mingueza would be asked to keep that standard and provide dependable cover when needed. There are currently no rumoured links for either Celta Vigo or Leipzig.
