Porto attacker Luis Diaz is attracting major interest from across Europe.

Having seen an offer from Everton rejected by Porto last summer, the Colombia international now knows the Toffees aren't alone in their interest ahead of the January market.

Barcelona and this week's Champions League victors Liverpool are having Diaz currently scouted.

Bayern Munich, Chelsea, Tottenham and Roma have also had scouts posted this season to keep tabs on the attacker.

Porto will be reluctant sellers in midseason, though could be powerless to prevent Diaz from leaving with his contract carrying an €80m buyout clause.
