5 things we learned from Barcelona's pre-season tour

#3 Frenkie de Jong could be a real hit at Camp Nou

FC Barcelona v Arsenal - Pre-Season Friendly

Ernesto Valverde tried out over 25 players across Barcelona's five fixtures, and there was arguably no player who outperformed Frenkie de Jong.

The 22-year-old made a step up in his career from Ajax to Barcelona, and while many might have been fazed by the surreality of playing with such legendary players, Frenkie de Jong has taken it in his stride.

He has slotted in seamlessly to the Barcelona midfield and impressed all with his composure and technique on the ball.

Frenkie de Jong has a brilliant 'footballing brain', while also possessing the requisite close control, vision and ball distribution technique to succeed as a Barcelona midfielder.

Despite the fact that the Catalans paid €75m for his services, if the Dutch international continues with his trajectory, that fee would look minimal compared to the impact he would make.
