(Video) Chelsea, Manchester City withdraw from European Super League as Blues fans besiege Stamford Bridge

Multiple sources claim tonight that Chelsea and Manchester City are pulling out of the Super League, which could scupper the whole project.

BBC Sport reporter Dan Roan first broke the news for Chelsea, but it was confirmed by multiple sources, including The Times and The Telegraph.

Now The Sun is reporting that Manchester City had also decided to pull out, especially as they were the last club to sign on last night.

Chelsea are said to be preparing the official paperwork to pull out of their commitment to the Super League.

This would leave only 11 clubs: Juventus, Inter, Milan, Real Madrid, Barcelona, Atletico Madrid, Manchester United, Manchester City, Arsenal, Tottenham and Liverpool.

The news was greeted with jubilation by fans who had gathered outside Stamford Bridge to protest this evening, blocking traffic including the team bus.

Petr Cech got out to negotiate with the supporters and assured them he would take action.

There are two Italy internationals in the Chelsea squad, Jorginho and Emerson Palmieri.
