Liverpool will face Chelsea, Bayern Munich and Barcelona in the battle to sign Porto winger Luis Diaz, according to A Bola.
The Portuguese tabloid claims all four clubs are now pursuing the Colombian international, following his strong start to the season.
Diaz was a target for Tottenham in the summer, and it was reported at the time that he has an €80m (£68.4m) release clause, which may put off some potential suitors.
The 24-year-old is usually deployed on the left flank by manager Sergio Conceicao, cutting in onto his stronger right foot to get shots away on goal.
Diaz has been extremely prolific so far this campaign, having bagged six goals in just eight league appearances, including the equaliser in the 2-1 win over Pacos de Ferreira at the weekend.
Whether Liverpool need another left-winger, considering they already have the likes of Sadio Mane and Diogo Jota who can play in that position, it does seem unlikely, but we shall see how this transfer story develops.
