Dutch legend Wesley Sneijder is worried Jurrien Timber will struggle in the Premier League because he "loses every header".
Timber, 22, is on the verge of completing a £38.7million move to Arsenal after winning several team and individual honours with Ajax. The Gunners will pay £34.3m up front for the Netherlands international, 22, with a further £4.3m coming in add-ons.
Timber will become one of the smallest centre-backs in the Premier League at 5ft 10 inches. Although Sneijder thinks Timber is a "really good defender", he's concerned the incoming Arsenal star will struggle in the air against English football's biggest strikers.
