Carlo Ancelotti thinks the owners of Manchester United and Arsenal are more interested in money than the success of the club on the field.
Ancelotti, who is now manager at Bayern Munich, had a spell as boss of Chelsea between 2009-2011 and his side will play the Gunners in the last-16 of the Champions League this season.
The Italian thinks that managers such as Sir Alex Ferguson and Arsene Wenger have been allowed time in their jobs because the owners of the clubs are more concerned about making money than who is coaching their team.
“In the big clubs it is difficult to stay a long time because the expectations of results are so high,” Ancelotti said. “Madrid’s history and demands mean that if a coach doesn’t win trophies, a change is made. You have to respect that.
“It’s true that there are other clubs like Manchester United, where [Alex] Ferguson was there many years, and now Wenger at Arsenal.
“These cases are different, as their owners are from the US and they are more interested in the financial aspect than in who is coach.”
