"Just before he moved to Liverpool, our models suggested that Diaz should theoretically hit the ground running, largely due to the similarities of playing styles between Liverpool and Porto," Andy Forrester, product manager at AI Abacus, tells
Sky Sports.
The model factors in just about every measurable aspect of a team's style of play. Liverpool are better. But Porto try to do the same things. "In terms of tempo, high press, counter-press, defensive line and build up, the two teams are almost identical," adds Forrester.
This modelling looks beyond the formations that would have suggested Diaz was playing in a 4-4-2 at Porto. "The reality of it is that when you watch Porto, they play so high in possession anyway that he practically takes up the same positions on the pitch.
"We simulated targets that Liverpool had been linked with and Diaz came out as the clear winner in having the highest predicted chemistry with the Liverpool squad. It specifically predicted he would link up well with Andy Robertson, Diogo Jota and Harvey Elliot."
Diaz's counter-pressing score in the AI Abacus model was even better than Sadio Mane - just below that of Roberto Firmino. Significantly, it was "a lot higher than a lot of the other targets they had been linked with" - another reason why he was the right choice
