Brentford boss Thomas Frank believes Chelsea have paid an 'insane' amount of money to bring Mykhailo Mudryk to Stamford Bridge.
The Blues pipped Arsenal to the Ukrainian winger's signature last weekend as Mudryk completed his €100m (£88m) move, and he is line to make his debut against Liverpool on Saturday.
Frank was asked for his opinion on the transfer at his pre-match press conference ahead of Brentford's trip to Leeds on Sunday, and admitted it is hard to comprehend how expensive players are becoming nowadays.
