Brighton boss Roberto de Zerbi is happy with the form of Pervis Estupinan.

However, he also feels there's more to come from the Ecuador fullback.

“Yes, but his improvement now is clear for everyone. There are not too many left-backs as good as Pervis Estupinan at this moment," said De Zerbi.

“[He is] very, very important to us. He played a great second half at West Ham, the first half as well, but maybe his position wasn't the best position for him in that situation.

“In the second half he played more or less in the same position but ten metres further inside, with great line pass(es). Playing three defenders with one of the three a full-back I think can give us something more than Igor, for example. He (Pervis) can attack better than Igor, he can find different solutions. I'm very happy when I can play with Pervis."
