The Blues remain two points adrift of leaders Liverpool in the table with four games left to play, one of which is a showdown between the sides at Anfield.
"We are in a situation where if we win all of our games we might have a chance," Cech told the club's official website. "We will concentrate on ourselves and we know if we win our four games we might have a chance.
"If we don't, it will become more difficult because time is running out. For the neutral fans I think this is the best that could happen in the Premier League because it will be really tight until the last game."
Chelsea also remain in contention for the Champions League trophy as they prepare to face Atletico Madrid in the semi-finals later this month.
