Liverpool star Andy Robertson has praised Luis Diaz’s impact since his arrival from FC Porto in the January transfer window.Diaz moved to Anfield for a fee of £37million and has added a lot more freshness and directness to the Reds attack.The Colombian did not take too long to settle into the style of play at Liverpool. He has put in some eye-catching displays whenever he has been given the opportunity.Diaz came off the bench in the Merseyside derby against Everton this past Sunday. He caught the eye with a ridiculous piece of skill to control the ball with his backheel and then breezed past Seamus Coleman.The Tactical Times@Tactical_TimesLuis Díaz strolls up to the derby and just attacks it.
