Silva said: "Disappointing. Performance first half was that we were not there at all. That is the reality. The first time that has happened since 2021, the way we play and start the game. You can start the game on the backfoot sometimes but it was not clear what happened. Too slow, not solid enough, everything we planned for the game wasn't there in the first half.
"The reaction was there in the second half but we woke up too late.
"It wasn't the fault of the three players that came off at all, in that moment if I could change more I would have. I don't want to do all the subs in that moment but it wasn't them. We needed Tom Cairney to keep us calm and I knew he would do that with better circulation in our build-up and organisation. In that moment I made those substitutions because we needed a different type of things.
"We were not clinical in the second half. We created enough to have a different result after a bad first half but football is from the start and the damage was already there. Our aim was to not let the damage get bigger in the second half and we did that. We have to go to the next one.
"They have to be disappointed with us and they have all the reason to be. In most moments they have been pleased with us and proud. We are in this fight together and I know they will be there next Saturday to support the team. Tonight, they should be disappointed with us because we didn't perform as we should do."
