Manuel Pellegrini believes a player like Lionel Messi would cure the issues of Manchester City.
He said: "First we need to find another Messi! He makes the difference, without doubt, like (Cristiano) Ronaldo at Real Madrid.
"But last year Barcelona didn't win any titles. Messi is an important player but it's not just Messi. You need a lot of things around him to be an important team.
"I said when we played against Barcelona we were very unlucky, that both years we had to play against the best team in the world, with Messi included.
"I think what Barcelona did against Bayern is no surprise for anyone, and not to me. Now they are demonstrating that I was not so wrong in what I said."
Pellegrini hopes that Sergio Aguero can be that player for City. Aguero has been outstanding this season, but he has also dealt with injuries.
"It's important for Kun to improve every year, to play all the games," Pellegrini said. "Maybe next year we'll see another Kun because he is working differently, he is growing every year.
"I hope he will be as important here as those players are at their teams."
