Scrum-half Dan Robson says choosing to leave Gloucester for Wasps is one of the hardest decisions he has ever made.
The 22-year-old will switch Premiership clubs in the summer, bringing to an end a five-year association with the Cherry and Whites.
"People think you've just got to make the decision and it's comfortable. It's a lot tougher than it seems.
"Gloucester have given a lot to me over and it's been great," Robson told BBC Radio Gloucestershire.
"It was one of the toughest decisions I've had to make, but it had to be made.
"Unfortunately, it means leaving Gloucester, but we've still got a long way to go this year."
Stoke-born Robson started playing for the Kingsholm outfit in 2010 after a spell at Hartbury College and has made 79 appearances.
He opted to move to Wasps after struggling to displace Scotland half-back Greig Laidlaw, but has found himself on a good run of form, scoring three tries in his last three games.
Although his time with Gloucester is coming to an end, Robson insisted his focus is still with the club and he is aiming for silverware before he leaves.
"The ambition has always been there since I've been at the club. It's a short career so you want to win things while you're playing," said the former England Under-20 international.
"But the ambition is going to feature a bit more when you're leaving at the end of the season.
"It's something you've got to work with and I'll give my all for the rest of the season and hopefully we can win something."
