Wolves were beaten 4-3 at Molineux, though pushed Chelsea all the way in the second-half.
Pereira said afterwards: “What a second half! In the first half, we conceded the first goal and after, when I looked at the team, the players were a bit lost and we concede a second goal and after a third goal. I assume the responsibility, because it’s my responsibility.
“We changed a lot today, 11 players, we played with 11 players that have not been playing for long time, so it means the connection and the rhythm for this kind of game is not easy.
“At half time, we spoke about it, and I said to them, it’s my responsibility, but I want to see my team, I want to see tactical organisation, and I want to see the spirit that we have as a team. In the second half, we won 3-1 and the goal that we conceded was a pity, and we had the chance to score two more goals, and we deserved it.
“I’m very happy – not with the result, of course – but with the spirit that we showed in the second half and with our supporters, because they were very important for us. We felt from outside, the energy that we need to compete and to change the situation.”
Pereira also stated: “We are in a bad moment, but the thing that gives me the confidence and the feeling that we can do it, we can change everything with a win, is the spirit of this team.
“The spirit that the team shows even losing 3-0, it’s not easy for a team losing 3-0 in this situation, and showing in the second half the quality and the spirit and how they competed with Chelsea, pushing them to the last third, creating problems – scoring three goals is not easy.
“If we don’t have character, if you don’t have quality, then we cannot do it.”
