Chelsea manager Andre Villas-Boas has claimed that Manchester City's squad is better than his own.
The Premier League leaders have invested hundreds of millions of pounds in players over the last few years, including David Silva, Edin Dzeko and Samir Nasri.
"We like to promote talent, but I don't think you can compare the two squads, to be fair," said Villas-Boas. "I think theirs is a lot better. When the top team has access to buy from their title rivals, you can build something extraordinary."
Chelsea travel to West Bromwich Albion in the Premier League on Saturday.
