Former Ajax captain Siem de Jong is backing Frenkie de Jong for success at Barcelona.

Frenkie de Jong will join Barca for a fee rising to €86m.

"He is really good on the ball," Siem de Jong told Omnisport.

"He isn't scared. Even sometimes in the back, he makes his actions. He is strong on the ball and won't lose it.

"If you see him, a lot of Ajax's build-up starts with him. He creates openings for other team-mates. He is a unique player in this time. He can really create things that others can't."
