5) Harry Kane (£40m)
With just one good season under his belt, Tottenham youngster Harry Kane could already cost an absolutely mad £40m, having been linked with a move to Manchester United.
6) John Stones (£30m)
Wanted by Chelsea in a £26m move, it could be that Everton defender John Stones could end up costing more than £30m as his club are desperate to keep him, even though he’s only played a season and a half as a regular in the Premier League.
