Right, Boilesen. In my eyes a definete NO GO.
Has been with Ajax for 3/4 years now, and his played only 1 season with the first team. Well, one season, maybe a quarter of it. Was out due to injury from October till April. Not on 1 injury, no, he had three consecutive injuries that plagued him for months, each of them. Solid defender, likely to replace Vertonghen if Ajax can't get a hold on Muniesa from Barcelona 'B'. Very little experience and only playd 5/6 matches last year. Can play as LB aswell.
Nat the fastest guy around, not the most agile player, passing is good but his technique is way below par. Good strength and stamina but very injury prone based on last season. Good heading and jumping and great tackling skills.
But this is all based on lets say 20 games in total. But in my eyes he is not even on a level to play in the Eredivisie for a full season, needs years of experience to even cope in the EPL.
