Bayern Munich star Arjen Robben feels Manchester City will be successful - if they do not chop and change managers.

The Dutchman, whose Bayern Munich side host City in the Champions League on Tuesday, was part of the Roman Abramovich revolution at Chelsea.

In the four years since he left Stamford Bridge, he has watched the Russian oligarch sack four different managers.

Jose Mourinho, Avram Grant, Luiz Felipe Scolari and Carlo Ancelotti have all been dismissed by Abramovich - and the winger is adamant that regularly wielding the axe on managers only serves to hinder the pursuit of top prizes.

He said: "The similar aspect between City and Chelsea is the financial investment.

"Abramovich entered with a show of force and now the Arabs have repeated that at City.

"But money doesn't guarantee victory and City need to be patient with their coach for this new project of theirs.

"Last season they won the FA Cup, but there can be any number of unforeseen dangers in a season and particularly in a debut season in the Champions League.

"It is working through these dangers which will make the squad stronger."
