Jurgen Klopp has hailed Trent Alexander-Arnold's "relentless" attitude at Liverpool and challenged the club's fans to come up with a song for him.
The England right-back extended his stay at Anfield by signing a new five-year contract on Saturday , keeping him on Merseyside until 2024.
Alexander-Arnold has become a key member of Klopp's Premier League-leading side since debuting in October 2016 and will now hope to help deliver a first title to Liverpool in 29 years this season.
Klopp is disappointed that the 20-year-old does not yet have a terrace chant on the Kop, although he believes one particular line of the renowned "allez, allez, allez" song relates to the defender, from whom he expects further development.
