Jurgen Klopp has shrugged off criticism of Liverpool's transfer business after he had previously said he would do things differently to big-spending clubs. Klopp's side this summer paid a world-record fee for a goalkeeper to sign Alisson from Roma in a deal worth up to £65m.

But two years ago, while Manchester United were set to spend a then record fee of £89m on Paul Pogba, Klopp had suggested he would quit the game if those large fees became the norm rather than the exception.
