15) Mehdi Benatia (AS Roma)
A rock-solid defensive player, AS Roma centre-back Mehdi Benatia is another top target for Manchester United in defence, while Chelsea are also believed to be stepping up their interest in him. The Moroccan international doesn’t look like he’d have any trouble settling into life in English football, and it would be great to see him make the move to these shores before the end of the transfer window.
