The Gunners were 2-1 winners on Sunday courtesy of a late goal from Danny Welbeck.
Arsenal looked set to be the latest big side to fall to the Foxes this season, after a Jamie Vardy penalty had given the away side a 1-0 lead.
However, a red card for Danny Simpson swung the game in the Gunners’ favour, as Theo Walcott levelled the scores in the 70th minute and Danny Welbeck scored a last-gasp winner to send his side to within two points of the leaders.
While the win delighted Cech, he says the most pleasing factor was Arsenal’s ability to overcome a side with 10 men, which can often be tricky to do.
"What I like about our win is that it is always tricky when opponents are down to 10 men,” he told BBC Sport.
“They have good organisation and are fighting for their lives. We managed to break them down and create chances.
“We kept missing chances but kept composure and kept coming. We had so many half chances where we could have scored more."
It will now be interesting to see if this result gives the Gunners the momentum they need to go on to make the title theirs this season.
After a strong first half of the campaign, many had feared they were falling away in the last few weeks, as a series of disappointing results threatened to end their title hopes once again.
The win over the Foxes could be the perfect countermeasure to that though, with manager Arsene Wenger sure to be hoping it can be the platform they need to secure the title in the remaining games of the season.
