Rhys Williams admits he was "scared" when he received a message from Jurgen Klopp asking to see him.
The young defender has been thrust into the Liverpool first team as they battle a hefty injury list.
Williams has played 13 times with Virgil van Dijk, Joe Gomez and Joel Matip all sidelined.
The 20-year-old only made his professional debut last year but is now an option in defence.
He revealed that Klopp summoned him with a Whatsapp message that left him "scared" - but it was only to offer some pointers.
He told UMM : “I'd probably say the captain or maybe Virg [are the most active in the WhatsApp group chat].
“Obviously [Van Dijk] has not been playing with his injury, so before every game he is wishing all the boys good luck and stuff like that.
“And the skipper [Jordan Henderson] is the one who is always replying first.
“There was one [message] recently [from Klopp] - 'can you come and see me please.' I was scared!
“But it was just to discuss some stuff that I could do better in games, so it was nothing to be worried about. But I was nervous.”
Williams has played domestically and in Europe for the Reds.
But the circumstances that led to his Premier League debut certainly were not ideal.
The centre-half was poised to be on the bench for the visit of Tottenham in December, but a late Matip injury meant he was thrown in.
“I was nervous because I wasn't starting at first, I was on the bench. And then Joel Matip was meant to play," he said.
“He had a problem with his back, so the boss and the first-team coach come to me and said 'be ready because you are starting, Joel has failed his fitness test.'
“So that was say five or six hours before training and I had to get my head together because that was my first game in the Premier League with [Harry] Kane and [Heung-min] Son up top.
“I was nervous but the boys helped me through it.”
