Harlequins director of rugby Conor O'Shea is hoping senior pros Mike Brown and Ugo Monye can help unlock winger Charlie Walker's full potential.

The 22-year-old penned a two year contract extension this week to kleep him at the club until 2017.

The former England U20 and Sevens international scored four tries during his breakthrough campaign last term.

And O'Shea, who watched his Quins humbled 37-6 at Wasps on Sunday, believes he is back to his best form once more.

"Charlie has recaptured the form that makes him one of the most exciting talents in the country," said O'Shea.

"He fits perfectly with the style we like to play and I am now hoping we will see him go from strength to strength and fulfil the incredible potential that everyone knows he possesses."

The twenty-two year old represented England 7s during the Hong Kong leg of the 2013 World Sevens Series and won a Grand Slam with the England Under 20s. He is also a Junior World Cup finalist.

Walker added: "I love the way we play and I am looking forward to improving my game with the coaches and senior players such as Mike Brown, Tom Williams and Ugo and achieving the results we want as a team and a club.”
