4. Jan Vertonghen Ajax to Tottenham Hotspur
Versatile, technically gifted, comfortable on the ball, and creative. Not always attributes you would associate with a Premier League defender but with those very skills the 2012 Eredivisie player of the year could prove to be the best signing of the bunch. If Spurs boss Andre Villas Boas wants his side playing from the back and pushing a high defensive line then he would struggle to find a better footballer to slot into the heart of his defence. Capable of interchanging positions at will, Vertonghen is the most modern of footballers and has his best years well ahead of him. Vertonghen also scored 8 goals in 31 Eredivisie appearances last season highlighting just how much the former Ajax captain bought to the side. Spurs fans should expect more of the same from their new purchase.
