The 19-year-old has had an impressive breakthrough campaign for Liverpool, featuring in nine Champions League matches, including the quarter-final win over Manchester City and the semi-final victory against AS Roma, and 19 league games.
"I found out this morning, just before we came out to Marbella. The manager came and spoke to me just as we were getting on the plane," said Alexander-Arnold, currently in a training camp in Spain.
“He asked me if I knew anything about the squad or anything yet. I said, ‘no’ and he said, ‘Have you got anything planned around the time of the World Cup?’ I was like, ‘No, no holidays or anything... “He said to me, ‘OK, good... You’re in the squad!’ It was a really proud moment. On England’s behalf, it was nice of them to let the manager tell me.”
Klopp, who handed Alexander-Arnold his Liverpool debut in 2016, was equally proud of the teenager and says the call-up was a great way to top off a special season. “(England manager) Gareth Southgate gave me a call this morning (Wednesday) and told me that I am allowed to tell him...” Klopp said.
“So, in the bus to the plane, I saw Trent for the first time... I had the honour of telling him and it was nice to see the reaction in his eyes. It’s fantastic, it’s well deserved, what a season. What a season! “It’s just a wonderful little piece more which makes this season special, even before the last game.”
Liverpool is in contention to win its first European title since 2005 when it takes on holder and 12-time winner Real Madrid in the Champions League final in Kiev on May 26.
