After conceding first, Fulham fought back to win 3-1 thanks to goals from Harry Wilson, Emile Smith Rowe and Kevin.
Silva said afterwards: “First-half, we didn't play at our best level, definitely. It was slow. Off the ball, we were too open in some moments, not compact and narrow enough.
"On the ball, we did not have the normal dynamic that we have to be able to create much more chances. I told the players at half-time what we should have done differently. Of course, we changed for the second-half and we won the game and I think we deserved it.”
Silva also stated: "It's always tricky to go from Chelsea and Liverpool to play against a very good side from the Championship. Part of our preparation was in that direction - to not underestimate them, to not allow them to think it's guaranteed for us to be in the next round, because I know how this competition is if you're not at your best level.
"In the second-half we were, and of course when we are at our best level, our collective quality and individual quality got us on top and because of that, we won."
