City have delved deep in the current transfer market by spending over €116 million on Fernandinho, Jesus Navas, Alvaro Negredo and Stevan Jovetic so far.
Cech, who arrived at Chelsea as part of Roman Abramovich's spending spree in 2004, acknowledged that while City are shaping up to be dangerous rivals with the new signings, their spending will be for naught if they don't work as a team.
"Manchester City have spent money to challenge. That's the reality of the situation,"Cech was quoted as saying on The Sun, "so, at Chelsea, we know it's going to be a tough season but we're here as well and working hard to be ready for the challenge.
"Money has never won anything. You can spend as much as you want but you must build a team first.
"Yes, City have huge competition for every place. They have a new manager, new expectations and new motivations - and, if they build a team, they will be a tough opponent and rival for us in the Champions League and for the Premier League title but so will Manchester United. So will Arsenal, Tottenham and Liverpool."
"We'll try our best to win the league. Our aim is to do the very best we can. We know what our objectives and targets are and will go game-by-game and try to win everything we can and then see."
Chelsea will travel to Indonesia in for the third match in their Asia tour, where they will face an Indonesia All Star side on 25 July.
