'It's true that he has ups and downs during matches': Barca boss defend Dest recent performance

Koeman says that Dest had a good start at Barca but he still needs time to adapt and improve his concentration and aggressiveness.

The coach believes that Sergino has the right to make some mistakes during matches.

The Dutchman says he's not disappointed with the right-back.

"It is true that Sergino Dest has ups and downs during matches, but he started very strong and needs time to adapt. Like any player, he has the right to make mistakes, and [needs to] improve his concentration and aggressiveness to defend," Ronald Koeman has said during the press conference ahead of the Athletic Bilbao game.

"Dest has to exploit his qualities, and I am not disappointed with him, not at all. "

Sergino Dest had a great start at Barcelona but his performances dipped with time. It might have to do with the fact that he's played many matches in a row and needs to rest.

In 18 matches for the Catalans this term, the 20-year-old has recorded one goal and one assist.
