Louis van Gaal has reportedly been advised to move for Jasper Cillessen if David de Gea leaves Manchester United for Real Madrid this summer.
De Gea is widely expected to join the Spanish giants, and Van Gaal called upon goalkeeping coach, Frans Hoek, to draw up a list of replacements.
Topping that list, according to The Mirror, is Ajax's Cillessen, who is the first-choice keeper for Netherlands and played under Van Gaal at the World Cup last year.
Cillessen will cost United around £20m, with the club expecting to fetch £30m for De Gea if Madird meet their valuation.
