Chelsea have offered Rooney a route out of Manchester United, but a bid was rejected by the Barclays Premier League champions despite the apparent desire of the striker to leave and there is some way to run in the bid for his services.
Jose Mourinho insisted the England forward is the Blues' only transfer target and, while praising Rooney, experienced goalkeeper Cech preferred to focus on preparing for the new season.
"Wayne Rooney is a great player but at the moment he's a Man United player," Cech said.
"We'll see what's going to happen. He's a great player. Let's see.
"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.
"We already have a few more players and a great squad. If the manager doesn't think we have enough he will try to get players in. It is only his decision.
"For players, we concentrate on getting fit and doing our best, to play as much as we can. That's all we can do.
"In football things are changing every day with every squad. As time goes on, every team can make some changes. Anything can happen."
