Cech, who speaks five languages, broke the Premier League record for clean sheets on Monday, notching his 170th career shutout as Arsenal defeated Bournemouth 2-0.
"I also speak to the full-backs in Spanish, to (Laurent) Koscielny in French and to Per (Mertesacker) in English because for him it is the same as me," Cech revealed after reaching the milestone.
"Sometimes the foreign player wouldn't know what you say. That's when you realise sometimes it's easier to say it in their language than hoping they will understand. It can happen.
"You have to be consistent in your work, consistent in your performances because if not then you might not have as many games as you would like, less games you play then less chances to have a clean sheet."
