Arsenal goalkeeper Cech is certain the return of injured key players will win the title for Arsenal.
The 2-1 win over City on Monday, means Arsenal have only lost one of their last 11 matches.
The absence of key players did not deter Arsenal from the feat and Cech believes they can win the title by May.
He told BBC Sport: “The squad is very strong and once we have everybody available, the manager can use every player the way he likes. That will be to our advantage and we’ll be able to go all the way.
“We’ve been through the season with plenty of problems.
“Everything isn’t going as smoothly as we would like it to. We can’t avoid injuries – sometimes you have more, sometimes you have less – but we showed that even with the unlucky injuries at the moment that we manage to win games.
“I believe we will benefit from players coming back into the team, once they are fit.
“The season is long and anything can happen. But if we stay where we are until March or April, then we have the chance to win the league.”
