Chelsea forward Salomon Kalou has told big-spending Manchester City they cannot buy this season's Premier League title.
However, Kalou believes City will need more than just high-profile transfers to dethrone Premier League champions Chelsea and the 24-year-old expects the Blues' togetherness will prove the difference this season.
"Just because you bring in 10 new players every year doesn't mean you are going to finish top of the table," Kalou said.
"City did the same thing last season and finished fifth and I am not sure if they'll be any stronger this time.
"Spending a lot of money on new signings doesn't guarantee anything. There are still teams like Manchester United, Chelsea, Arsenal and Liverpool who will always be at the top. Manchester City can do well because they have brought good players in this year but the reality is on the pitch. You can have 10 new players and it doesn't guarantee you anything.
"It's good to keep the same team. This is the squad that won the league and FA Cup double last season. We know how to win. We'll try to bring some youth players through and they will show their quality. From there, we will have a good squad ready for the Premier League and Champions League.
"We are still the team to beat; we are the champions. But everyone will come hard to try to beat us. Since I've joined Chelsea [in 2006], we always fight with Manchester for the title. This year, we will be fighting with four good teams – Manchester, Liverpool, Arsenal and Manchester City."
Chelsea are due to bolster their own ranks with an £18.2 million deal to sign Benfica midfielder Ramires, with Deco expected to leave Stamford Bridge to make space in Carlo Ancelotti's 25-man squad.
