Llanelli's director of rugby Phil Davies believes he has signed a future international who will only benefit from working with Scarlets backs coach Robert Jones, the former Wales scrum-half.

Davies said: ''Martin possesses a great passing game and he will add depth in this position. We believe he is a future Welsh star.''

Roberts made his Ospreys debut in 2005 but is now behind former New Zealand international Justin Marshall and Welsh Grand Slam-winner Mike Phillips in the pecking order.

He will be competing with Sililo Martens for the scrum-half jersey after the Tongan swapped Sale for the Scarlets when Peel's move to the Guinness Premiership was confirmed.
