Jose Mourinho has lauded Newcastle, Crystal Palace and Bournemouth signings.
The Chelsea manager is looking for his side to retain their trophy but knows it will not be easy.
He picked out three new signings made by Newcastle United, Crystal Palace and Bournemouth as players who are good enough to play for his side.
He said: "There will be more times when the non-title contenders win matches against the title contenders.
"It's also difficult because they have players who could play in our teams - Cabaye could play for Chelsea, Wijnaldum could play for Chelsea, Gradel could play for Chelsea."
Chelsea have held back in the transfer market this summer, seemingly no longer the free spending side they were.
His comments are a nice compliment to each of the signings, that they are good enough to play for the champions of England - and highlight the talent Palace, Newcastle and Bournemouth have bought respectively.
Bournemouth are a newly promoted side, and their ambition, having spent more than £20 million, gives them a real chance of staying in the division.
The problem Chelsea face is they need players who are not just good enough to play in their team, but exceptional players able to dislodge those already holding down a first team spot, as evidenced by Colombian international Juan Cuadrado's struggle to make an impact.
