Wasps did everything to keep Vunipola

Director of Rugby Dai Young revealed London Wasps did everything they could to keep Billy Vunipola at the club but “pressure for family reasons” pushed him to join his brother Mako at Saracens.
The North-London club announced yesterday that the 20-year-old No.8 agreed terms to a long term contract with the 2011 Premiership Champions from next season.
Vunipola was named in the England Saxons squad last week but will train with the England EPS ahead of the Six Nations as Leicester Tom Croft carry on his return-to-play programme.
In a statement, Young said Wasps “offered him the contract he asked for and that they didn't see any reason for him to leave”
He said: “We are clearly hugely disappointed. Billy is a player that the Club identified some time ago as one with huge potential and he's been developed by London Wasps, despite a period when he struggled with illness and injury, into one of the brightest young talents in English rugby.”
“During our contract talks, the player had been adamant that he did not want to leave the Club but we know he was under pressure for family reasons to go and join his brother at Saracens. We did everything in our power to keep Billy. We offered him the contract he asked for. He is playing regularly and he has already got international recognition, so we didn't see any reason for him to leave. Although we had heard the whispers about him going to Saracens, we were only officially informed yesterday afternoon that Billy was leaving and he had previously signed for them.”
“Although we are bitterly disappointed right now, it is only fair for me to say that I believe that Billy will become a top quality international player for years to come and we wish him the best with his career. There is a long way to go in the season and I am sure he will give his all for Wasps in the coming months.”
