Manchester City midfielder Bernardo Silva admits their 1-1 draw with Chelsea is a "setback".
A late Rodri goal canceled out Chelsea's opener scored by Raheem Sterling.
Bernardo said: "Two different halves, first half was not good enough and very disappointing, the second half was a reaction from the team.
"But, it's not good enough to play for 45 minutes so we have to try do better next Tuesday [against Brentford].
"It is good that the game is in three days to react, but of course it is a setback as one point at home is not good enough.
"Chelsea are a team with a lot of quality, it's not by chance that they create so many difficult chances.
"The rhythm and the pressing was not good enough and when you play against the quality of Chelsea they punish you - they scored one and could have scored one or two more.
"The reaction from the team was very good, but a bit late."
On the title race, he added: "It is entertaining for the people, but for us it is a setback and it is very tight - everyone can go for it.
"Our job is to perform at the highest possible level."
