Manchester City boss Manuel Pellegrini says they need to splash the cash this summer to keep up with Europe's elite.

Pellegrini has warned they cannot stay idle.

"Well, it is just the way of thinking, that big teams need to sign a big player. It is very difficult to do it every year - but every two years you must do it.

"I'm not just talking about Manchester City. You see Real Madrid, Manchester United, Chelsea, Barcelona and Bayern Munich - all the big clubs - they all do it. It is important to have big names."
