The centre-back was one of Southampton's key players last season after joining from Lyon last summer, leading to speculation that he could be on his way to a bigger side. Premier League trio Liverpool, Arsenal and Tottenham have been keeping tabs on the 24-year-old's situation at St Mary's Stadium, where there seems to be an exodus of key players. The Saints have already parted ways with three players this summer, with Luke Shaw joining Manchester United, while Adam Lallana and Rickie Lambert have signed for Liverpool.
