Jurgen Klopp is adamant Luis Diaz will become a rich source of goals for Liverpool after suffering the most gruelling pre-season of his professional career.
Diaz could not have made a more positive impression during his first months in England.
His performances, after the £37.5million move from Porto, were one of the main reasons Liverpool won both domestic cups and reached the Champions League final.
The Colombia forward scored six times after making his debut in January but there was always a feeling that his return could be even better if he had a little bit more composure in the penalty area.
