Liverpool boss Jurgen Klopp has admitted that he has not experienced a more extraordinary turnaround in footballing fortunes than that of Alberto Moreno.
The Spaniard appeared to be set for an exit having made just two Premier League starts last season, but has regained his place ahead of stand-in left-back James Milner this campaign.
Moreno has now established himself as a fixture of Liverpool's team, and earned effusive praise from his previously unconvinced manager.
"I never had something like this, I never had it to be honest," Klopp told Liverpoolfc.com. "This season is not a surprise, the surprise is how dealt with last season. There was not one bad word in the whole season.
"Yes, he was in my office, yes, he asked what he could do better, and we spoke about the things he had to do better.
"On the other hand, Milly played really well and he's a machine, he could play every two days, so there was not a lot of reasons to make the change then he had no rhythm.
"I felt that it was unfair after the season, I thought, 'Damn, we didn't use him often enough'.
"Before the season, he came to my office and asked again and I told him we get another full-back but it was not the plan for Milly to be in the full-back race again so you decide what happens - and he decided it.
"He's now a much better defender, that's how it is, he's a brilliant footballer. When you see him shooting here, you think he cannot shoot - he shoots like crazy! It's unbelievable how good he is! In the games so far, obviously, it didn't settle.
"How he reacted on last year is really, really good."
