"We saw that he had the Barcelona profile," said Abidal at the player's official presentation.
"He is a left-footed player who can play on both wings, while he can also play as an attacking midfielder.
"He has a big future ahead of him."
Abidal also spoke about Barcelona's summer business as a whole, saying he is pleased to have secured Malcom, Clement Lenglet and Arthur Melo.
"With the three signings that we have, we have everything and we especially have a future," he said.
