Williams has almost 20 appearances for Liverpool’s first team which includes six in the Champions League and nine in the Premier League.
The young centre-back was sent on loan to Swansea City at the start of the campaign to further have experience playing first-team football, but after only making seven appearances he was recalled in January, serving only half of his intended season-long stint.
Lewtas feels that Williams’ experience playing senior football comes in handy in the Under-23s as he improves the performances of his fellow starlets.
Another player Lewtas feels has been helpful in that regard is Leighton Clarkson, who, like Williams, went on loan at the start of the season only for his spell with Blackburn Rovers to be cut short after seven appearances in January.
“It’s very obvious from his (Williams’) quality as a player, as a boy and also as a leader”, Lewtas was quoted as saying by Liverpool’s official site.
“I think he’s really helped Jarell Quansah and Billy Koumetio, he has helped Conor Bradley and Owen Beck and the backline.
“Rhys has earned the right to be with the first team every day, so he sees that level and he has brought that level of maturity and experience down with him.
“I would also say Leighton Clarkson has also brought his loan experience with him as well, in terms of being around senior players.
“Those two have brought an extra level to us in terms of how we want to play and as people and characters as well.
“They have been superb.”
Since returning from his loan spell in Wales, Williams has played every match for the Reds Under-23s bar one in the Premier League 2 Division One and scored in last weekend’s victory against Manchester United.
