City's destiny is now out of their hands following a dramatic 3-3 draw with the Toffees on Monday (04.05.26) but the coach says they must win their last four games to keep the pressure on Arsenal - who now have a five-point lead having played a game more.
Guardiola said: "We need to win our games. Now it is not in our hands.
"If they win their games the title will be for Arsenal. Now have to win our next game, we have to recover well for a series of games, and this is what we have to do."
City did salvage a point after Jeremy Doku's last-gasp equaliser and Guardiola urged his team to keep going despite the setback.
The Spanish manager said: "It’s better the point than no point, but it (would be) better to win the game that we needed.
"I know it was in our hands and in Arsenal’s hands as well, it depended on goal (difference). Now it’s not, but we have a responsibility. We play Brentford (at the weekend) and we continue and we will see what happens.
"Better effort cannot be possible. The message is the same as the day before. We have four games left and a final – win the games. That is the message. We play for that, even with difficulties for many reasons."
Doku echoed his manager's words after the "painful" dropped points.
The winger said: "Good that we came back because one point is not bad in games like this.
"We know that one point can be important at the end. I’m happy to score and happy to help the team.
"We will see. It feels painful now. There is still a lot of games to go. We lost two points today. We will keep on fighting – we owe it to ourselves and to our fans."
