Manchester United seemingly missed a hint from ex-assistant manager Carlos Queiroz before Liverpool beat them to the signing of Porto 's Luis Diaz.
Jurgen Klopp 's side are set to snap up the electric winger before Monday's deadline for £50million, leaving the Red Devils wondering what might have been after the 25-year-old was compared to none other than Cristiano Ronaldo.
Queiroz coached Diaz for Colombia until December 2020 and compared his journey to that of Ronaldo's, who also came to the Premier League from Portugal.
