5. Juan Foyth, 19, Spurs, Centre-Back
An intelligent ball playing Argentinian centre-back brought in as cover for first teamers Toby Alderweireld and Jan Vertonghen, this could be a significant signing for Spurs. At 19 and lacking real first team game time not to mention the fast pace of the premier league, Pochettino will embed him in slowly and in games where Spurs will dominate the ball. A good season would be to get 15-20 appearances under his belt, whilst climatising to the physical nature of the domestic cups.
Transfer fee: £9m
Likelihood of becoming the next Pochettino: 7/10
