Chelsea manager Jose Mourinho has claimed UEFA's financial fair play (FFP) rules are protecting the game's established giants and halting newcomers hoping to break into the European elite.

The Blues, Manchester City and Paris Saint-Germain are among the clubs to have muscled in alongside the continent's traditional powerhouses with the help of huge investment from overseas owners.

The FFP rules -- introduced during the 2011-12 season -- were put in place to ensure clubs work within their means and do not operate at huge losses subsidised by their benefactors.
