4. Alex Oxlade-Chamberlain
Bear with us. The Ox is yet to fulfil the huge potential he showed when he first moved to the Emirates back in 2011. But the Gunners wide man is still young at 23 and is crying out for a starting spot in a decent side to improve his game. West Ham could offer that to Chamberlain, who can also play at the centre of midfield where the Hammers could do with some competition for places. If he could add more goals to his game he could still one day become world class. Arsenal could sell up for as little as £25m in the summer.
