"This is a good match for us to learn something [from]. There is always something important to learn. Now is the moment to react.
"It was a bad afternoon but it was in the past and we must look forward.
"It is always important you forget nothing - the good things and the others. We did some things in the wrong way, which we need to improve.
"We need to continue doing what we did well before [the Manchester City defeat]."
