Silva accepts Chelsea live at a different level, but insists they can match the Blues on the pitch.
The manager said, "Off the pitch, what they have been doing.
“The team had a very good last season and won the Conference League, they were the favourites, but won the (Club) World Cup as well, and were able to strengthen the squad.
“Even their attacking line – Estevao, (Liam) Delap, Joao Pedro, and probably more is coming, probably Garnacho is coming too. I think it speaks about themselves and the individual quality they have.
“Off the pitch is a completely different world. They are in a different world."
Balance everything
Silva also said, “They are capable to do things off the pitch which we are not – our aim is to balance everything inside the pitch, to balance everything during the 95 or 100 minutes that we are going to play against them, like we did last season both games.
“Two great games, really balanced, emotional games, late goals for us at Stamford Bridge, (and) after for them at Craven Cottage.
“But the way we faced them, the way we matched them, is what we are going to try to do again, to balance the things on a matchday that are completely different off the pitch.”
