Manchester United have already shown they can offer Frenkie de Jong something Barcelona seem incapable of providing.
De Jong's transfer to United has hit a stumbling block. The Manchester Evening News reported last month that the two clubs had 'agreed a deal in principle' for the Dutch midfielder, though progress since then hasn't been easy.
United are struggling to get the deal over the line. Meanwhile, De Jong has been moved into a centre-back position while on Barcelona's pre-season tour, a position change Xavi clearly believes can benefit his side.
