You'd think he'd know the place like the back of his hand, but nope!
And today he made his long-awaited return to the Bridge for the first time since moving across London to sign for Arsene Wenger's Arsenal over the summer.
With the Chelsea fans giving their former number one a great reception, Cech must have felt just like he was returning home, so surely he wouldn't get lost?
WRONG! Despite playing there hundreds of times, he somehow managed to go the wrong way when looking to enter the dressing room.
Thankfully he managed to figure it out before he left the stadium but we reckon he'll have wished he had got lost as Chelsea put two past the nine-man Gunners.
Not the return to west London that the Czech shot-stopper would have been hoping for, but there should be plenty of opportunities for him to put things right in the years to come.
