Chelsea manager Jose Mourinho has criticised UEFA's Financial Fair Play (FFP) regulations and claims it benefits only the biggest clubs in Europe.

In the last two summers, La Liga giants Real Madrid and Barcelona invested heavily in bringing Gareth Bale and Luis Suarez to Spain. Meanwhile, the Blues' league rivals Manchester United broke the British transfer record in capturing Angel DI Maria's signature earlier in August.

Chelsea have added star players like Cesc Fabregas and Diego Costa to their squad as they spent £93m in the last summer transfer window. However, the west London club were able to balance the books after allowing David Luiz to join Paris Saint-Germain, Romelu Lukaku to move to Everton and Demba Ba to Besiktas.

"I think Financial Fair Play is a contradiction because, when football decided to go for Financial Fair Play it was exactly to put teams in equal conditions to compete," Mourinho told Eurosport Yahoo.

"But what happened really with the Financial Fair Play is a big protection to the historical, old, big clubs, which have a financial structure, a commercial structure, everything in place based on historical success for years and years and years."

"And the new clubs - I call them new clubs, those with new investment - they cannot put themselves quickly at the same level. Clubs with new owners cannot immediately attack the control and the domination of these big clubs."

The Portuguese tactician has seen his side sit on top of the Premier League table. Despite that, the former Real manager insists Chelsea are not yet an established club in Europe.

"Chelsea is not an old, historical, huge club - but it's also not a club with a new owner. It's a club with the same owner for more than 10 years," the Chelsea manager said.

"A club with a very important history, with great stability too. And at this moment I think we are just below them. I can say we are a very good club with the ambition to be a great club," Mourinho concluded.
