Cech happy for Chelsea to continue buying
The threat of new signings is another added pressure but Cech says that goes with the territory of being at a top club like Chelsea.
He said: "If you end up with three more players because the club wants three more players, then your attitude is the same.
"You do your best to help the team to win things. If you buy players or don't buy players, personally I feel the same.
"It's the same for every team. You always want to have the biggest and strongest squad so you can challenge for titles.
"That's why you have a manager and sporting director to take care of that and you have to do the most important part and that's the work on the pitch."
