Schneiderlin is currently on World Cup duty in Brazil with Didier Deschamps' team, but has been linked with a summer move away from the Saints after becoming one of their stand-out performers during last season's highly-successful Premier League campaign. Ronald Koeman has already lost Rickie Lambert and Adam Lallana to Liverpool, as well as starlet Luke Shaw to Manchester United, and is determined to not let anyone else leave until he finds adequate replacements or their valuation is met. Former Saints boss and Tottenham chief Mauricio Pochettino is also eyeing up a move for the 24-year-old midfielder, but reports in Italy claim that Napoli have submitted an offer for his services.
