Argentine great Juan Roman Riquelme has no doubts about the quality of Alaves loan signing Facundo Pellistri.

The Uruguayan youngster has joined Alaves to the end of the season on-loan from Manchester United.

Riquelme admits he's a fan of Pellistri and wanted to sign him for Boca Juniors, where he is now vice-president.

"He is skillful. You can see that he is quite shameless when playing with the ball. That is important," said Riquelme, formerly of Villarreal and Barcelona.

"There are not many players like him and I think that you have to value him."
