Chelsea manager Jose Mourinho has denied the club's success is purely down to the money owner Roman Abramovich has pumped into the club.
"The formula spending equals success doesn't work in football," Mourinho told Barcelona-based sports daily El Mundo Deportivo on Saturday.
"Look at Inter Milan, they have invested huge amounts and haven't won anything for years.
"Porto and Liverpool have proved that money isn't everything."
Mourinho added: "If you compare us with teams like Manchester United and Arsenal, you see they are strong clubs based on decades of signing players that are now worth a fortune.
"If you compare the Chelsea squad with any other of those teams they are worth the same."
Mourinho said the only request he would make of Abramovich would be to ensure that his key players remain at the club.
"I would ask him to keep the players I've got, fantastic men who I don't want to lose. With all respect I wouldn't change (John) Terry, (Frank) Lampard or (Didier) Drogba for anyone."
Mourinho shrugged off suggestions Chelsea's style of football was dull.
"For me, being the team that has won most games, scored most goals and conceded the least means that we are spectacular.
"The result itself is spectacular and the fact that Chelsea are strong in all those areas means that we are spectacular side."
