Frenkie de Jong will officially become a Barcelona player on 1 July after joining the club from Ajax but will face a fight for his place at the Camp Nou, according to former boss Lous van Gaal.
The 22-year-old is coming off the back of a superb season with the Dutch side after helping them clinch a domestic double and make it to the semi-finals of the Champions League.
De Jong has attracted plenty of plaudits along the way for his performances, but Van Gaal reckons he will have his work cut out when he arrives at Barcelona.
