The Cottagers won 3-2, with three penalties given on the night, including a 94th minute winner converted by Willian.
"It's really important for us," said Silva. “We know the quality of Willian in that moment. Of course, last season it was my decision in certain moments to not change the penalty taker because it was a player that needed to score to get some more confidence to score in the other moments of the game.
“But we knew that Willian was always a taker for us as well. It was my decision for him to be the taker tonight, and it was nice to see him to take the responsibility. Two penalties, very good moments from him.
“Overall, his performance was really good, too. It's important – when you have these type of chances, we must score, and he did it in a very good style."
