Luis Diaz will be ‘scary’ prospect in full stride for Liverpool – Andy Robertson

Defender Andy Robertson believes team-mate Luis Diaz will be a “scary” prospect once he is fully into his stride at Liverpool.

There is an argument that the Colombia international is not doing too badly already having made the sort of impact only he and manager Jurgen Klopp could have dreamed of when he arrived as a opportunistic signing in January.

It is not that Liverpool were not tracking the 25-year-old – a host of clubs were, including city rivals Everton who tried to sign him from Porto as part of a failed swap deal with James Rodriguez – but they sprang into action when it emerged Tottenham were trying to get a deal done.

Within two days they had completed a medical in South America and clinched a deal for an initial fee of £37.5million and if his performances had not already demonstrated what a bargain that is likely to be, his second-half cameo in Tuesday night’s 3-2 Champions League semi-final second-leg win in Villarreal underlined it.

In a 45-minute spell, man-of-the-match Diaz completed 100 per cent of his take-ons, had a 90 per cent pass accuracy, four shots (the most of any player) and scored one goal in a display which helped turned around a 2-0 half-time deficit and eliminate the threat of the club missing out on a third final in five seasons with a 5-3 aggregate victory.

But Robertson believes the best is yet to come from the winger, who was in tears at the final whistle having put on a show for brother Jesus, who was in the stands to watch him.

“He has been special. We’ve tried to help him as much as we can, all the players. We know how difficult it is coming in in January,” said the Scotland captain.

With a full pre-season under his belt, I believe he will get better, which is scary, but what he has
