The arrival of Liverpool’s new No. 23 has provided an injection of positivity in the late-season run-in, with Diaz bolstering the attacking ranks considerably.
With Jurgen Klopp able to shuffle between a fully fit group of forwards in these closing weeks, Diaz has slotted in seamlessly, with five goals and three assists in 20 games so far.
The manager has attributed this to the easy transition from Porto to Liverpool, telling Sky Sports last month: “He did not have to change, that is why we have a really confident boy here.”
At Porto, Diaz was a dynamo down the left, with his 16 goals and six assists in 28 games prior to leaving in January making him a hotly anticipated signing.
He was a central cog in their emphatic start to the campaign, which, to their credit, the Portuguese side have managed to carry into life without Luis.
Saturday evening saw Porto seal a 1-0 win over Benfica, clinching the Primeira Liga title with only one defeat from 33 games so far.
With Diaz having played in more than half of the league games this season, he should then be delivered a winner’s medal as recognition of his efforts.
It is the second medal he has earned so far this term, having already won the League Cup with Liverpool, and he could still pick up three more before the end of May.
Porto’s triumph also brings a first major honour for Marko Grujic since winning the Serbian SuperLiga with Red Star Belgrade in 2015/16.
The former Liverpool midfielder did help clinch the Supertaca Candido de Oliveira during his initial loan spell with Porto – but that is the equivalent of the Community Shield.
