Marco Silva insists he hasn’t been surprised by Willian’s instant impact on his return to the Premier League this season – and he says the pair will wait until the end of the season to decide on the Brazilian’s Fulham future.

The former Chelsea and Arsenal winger is likely to have a prominent role in tonight’s SW6 derby after becoming a regular at Craven Cottage having signed on a free transfer once he cancelled his Corinthians contract last summer. The experienced winger has scored one goal and made three more in eleven appearances and Silva says the 34 year-old has added a different dimension a Fulham side that currently sit seventh in the Premier League table.

Speaking to the Athletic’s Peter Rutzler, the Fulham boss revealed:

“When Willian (signed), he was with me for some days … for him to feel something and for us to have conversations. It will be the same (in the summer). Our focus stays on one thing — to get our goal at the end of the season. When that arrives, it will be a time for me to speak with him again. We are both going decide what is the best for the club and for him as well.

On the quality, desire, ambition, professionalism — I did not have doubts. Never. When I spoke the first time with him it was enough. We know his quality. He has high quality and he is a top player. I can say now, because I know each day better, he is a great professional as well. A great guy. Fantastic from the first moment.”
