Brentford head coach Thomas Frank feels Chelsea have paid over the odds for Mykhaylo Mudryk and believes transfer fees being forked out are "insane."
The Blues landed the Ukraine international from Shakhtar Donetsk in a deal that could be worth £89million (€100m) as they continue to splash the cash following a takeover by a consortium-led by Todd Boehly.
Fellow winger Noni Madueke is also expected to arrive at Stamford Bridge from PSV, giving Graham Potter plenty of options to ponder.
Frank has questioned the fee the Bees' London paid for Mudryk and wonders how Potter can keep so many wingers happy.
"I think there is a lot of money around in the football world, especially in the Premier League," he told reporters ahead of the Premier League clash against Leeds United on Sunday.
"Looking from the outside, I think Mudryk is a very good player but 100million, that's a lot for a player who is showing great signs of potential but probably needs to do a bit more.
"Maybe that's just price-tags these days, which I think are insane.
"They've bought him and then there's rumours about the PSV guy as well. I think they have enough wingers but that is their issue."
