We've asked five experts to pick a player to watch for 2010-11, with their selections featuring on .tv all this week. Today, LFC Magazine journalist John Hynes chooses a teenager who recently became the youngest Liverpool player in history.

Player Profile: An all-action left-back with passion and commitment to match, Jack Robinson made the breakthrough into the under-18s' side during the 2008-09 campaign.

Since then he has established himself as a regular in Rodolfo Borrell's new-look team and was named on the bench for John McMahon's second-string in April.

An attack-minded full-back who is equally adept in defence, Robinson's form has been such that he was called up to Melwood for a training session, a move which led to him becoming the youngest Reds player in history when he appeared as a late substitute in the 0-0 draw at Hull City at the tender age of 16 years and 250 days.

John Hynes says: Unfortunately, it's not often you see a crunching tackle being made in the Premier League now. Officials rarely allow them.

Thankfully those who have regularly watched the U18s this season will have witnessed plenty, with Jack Robinson usually being the Liverpool player producing thunderous challenges.

His fierce tackling isn't the only reason why the full-back stands out. Despite still being at school he appears to possess the talent, commitment and attitude to forge a bright footballing future.

The fact that the England U17 international has already appeared in the first team at the age of 16 is proof of that. If he continues to develop as hoped he could one day become a regular at Melwood.

Jamie Carragher agrees with such statements. "He's really young and playing in a higher age group - for England as well," our vice-captain said in March.

"I've heard a lot of positive things about him. I wasn't even in the youth team when I first went full-time and he was a regular at 15 so it shows you he has something about him."
