BBC Sport's TV and radio commentators have picked a Liverpool player who will be worth watching out for in the next few months. Let's find out who he is.

Steve Bower: A few people within academy football told me about Rio Ngumoha over a year ago - tales of Chelsea's anger at losing the teenager, and a big gain for Liverpool.

Arne Slot's positive approach was immediate in involving him in first-team training, and then we saw him become the youngest player to start a game for the club in January in the FA Cup.

He's not 17 until the end of August, but I know internally there's huge excitement about him, and his goals in pre-season have heightened this.

Sometimes a young player sees an opportunity and, with Luis Diaz's departure, Ngumoha looks set to be in the first-team group throughout the season.

Conor McNamara: Back in January, I commentated for Match of the Day when Ngumoha became the youngest player to start a match for Liverpool - aged 16 years and 135 days old - in the 4-0 win over Accrington in the FA Cup.

To make us all feel old, the song that was number one in the charts the day he was born was Katy Perry's 'I Kissed A Girl'!

At the time, he was so unknown that I needed Slot to help me pronounce his name correctly.

But that FA Cup appearance was his only first-team game, and he never made the bench for a Premier League match through to the end of the campaign.

His form this pre-season suggests that should change this term.

He is still very young, and we know that competition for places will be severe at Anfield, but Ngumoha has a spark about him.
