Manchester City appear to be running away with the championship having recorded 11 straight wins while opening up an eight-point gap at the top.
Arsenal leapfrogged arch-rivals Tottenham into fourth place over the weekend with a 1-0 win way to Burnley.
The victory followed up the 2-0 north London derby win the previous week, however the Gunners sit 12 points behind the league-leaders.
But Cech believes City are still catchable and he thinks it the title will go down to the final few weeks of the season.
“We need to play game by game and not think too much about what’s going on around us because the only way is if you win your game you give yourself a chance, so this is what we have in our mind,” he said.
“We win our game and let’s see how the others are going.
“The teams at this moment who are above us, if they keep going and keep winning, then you can’t catch them, but you need to make sure that you win your game first and then let’s see what will happen.
“There are so many games to be played and so many points to play for and you don’t reach your goals after 13 games, you need to carry on for 30 games, with consistency obviously.
“There can be plenty of twists in the table as well because you win two games in a row you climb up and you can draw and fall out of the top four, so it will go pretty quick and is very packed up there and will be I think until the end of the season.”
Arsenal return to action at home to Huddersfield tomorrow (7.45pm).
