The Blues managed to beat Arsenal 2-0 at Stamford Bridge on Sunday.
He told his official website: “It could not have ended better. We claimed such a vital win, I helped the team with a number of saves and, on top of that, it was my 100th league clean sheet.
“I think we have cut off Arsenal by this win and they will find it only very difficult to erase the nine-point gap at this stage of season, especially with the tough games they are going to play yet.”
“The win is important because we have managed to respond to United’s win,” he added.
“We knew that if we had drawn with Arsenal, then they would have stayed infront of us on goal difference.
“That makes our win even more valuable as we have managed to cope with the pressure.
“For the rest of the season the decisive thing will be the consistency of results. The team which will drop least points on the way will win the league.”
