Jordan Henderson believes Joe Gomez's full potential remains to be realised.
The Liverpool defender has made an impeccable start to the season, playing in all four games as Jürgen Klopp's side maintained a 100 per cent start to the Premier League campaign.
An England recall was a natural consequence of the No.12's form and Gomez is now with the Three Lions ahead of fixtures against Spain and Switzerland.
And it is from the camp that Henderson - who signed a new long-term contract with Liverpool this week - declared that there is so much still to come from his club colleague.
"He's already very good but he can be even better," said the midfielder, who has been a teammate of Gomez since 2015.
"He's still very young. He's still improving, still learning and there's no better place to do that than at Liverpool with the players that he's got around him and the manager.
"I'm excited for him because I know how good he can be and he's got the right mentality as well. He's very mature for his age. His feet are firmly on the ground and he can be as good as he wants to be."
Disappointing news emerged from England on Tuesday after Adam Lallana sustained a groin strain in training and withdrew from the squad to return to Liverpool.
"Obviously for him it's devastating but for us as a team as well it is because he's a huge player, not only for England but Liverpool as well," said Henderson.
"So fingers crossed on the assessment it's not too bad and when we get back from international duty he's back and raring to go. But it's another little blow for him so it will be tough mentally for him."
