Brighton boss Roberto de Zerbi is delighted with the early impressions of Ansu Fati.
The winger is on-loan at Brighton from Barcelona.
De Zerbi said: "He played very well (against Ajax), but he can develop and become even better. Ansu's focus should be on enjoying football and finding the enthusiasm he had at the start of his career. Physically, I also think he can develop.
"He (Fati) is a special player, so is Joo Pedro. They play at 60 percent of their potential. I think they can get even more, and we're helping them. If they reach their highest level, they can help us win more games.
"This season we play a lot of games, then we have to rotate, but both Joo Pedro and Ansu Fati belong to our best starting eleven."
