Chelsea boss Graham Potter insists there's no issues with Financial Fair Play (FFP).
Potter was asked about the concern of rival managers after their 0-0 draw with Fulham.
He said, "Yeah, I do and I think you've got to look at all in terms of an investment, in terms of transfer fees and salaries. Sometimes you can sign a player for less of a transfer fee but the salaries are enormous.
"It just depends how you structure the contract, how you structure the deal. We're confident with what we're doing, I think the club has done a good job.
"Now my job is to improve the team."
