Iker Muniain
West Ham need more pace out wide. Whilst arguably their two best players play in those areas on the flanks; Dimitri Payet and Michail Antonio, neither of them are massively fast. They can move at a fair pace but cannot burn away from defenders and that’s where Muniain comes in. The Athletic Bilbao man has rockets in his boots and can beat most players in a foot race so he’d ultimately get the London Stadium crowd right out of their seats.
