Jurgen Klopp paid tribute to Luis Diaz after the £49m January signing overcame a tricky afternoon against Norwich City to score his first goal for Liverpool.
The Reds fell behind to a Milot Rashica strike shortly after the restart, prompting the German to introduce Divock Origi and Thiago Alcantara as Liverpool changed formation.
Moving Sadio Mane back to his natural left-wing position, Diaz went central alongside Origi as the Reds swapped to a 4-4-2 formation with Klopp admitting the change was necessary after Norwich had surprised them tactically.
