Alex Corbisiero says that it was necessary for him to leave London Irish for him to reach the heights he desires.
The 24-year-old will turn out for Northampton this season after spending five years with London Irish whom he made his professional debut with in 2008.
The prop was capped by both England and the British and Irish Lions during his time with the Exiles, but he insists that he will now develop even further at a club fighting for top honours, and as such he has left for greener pastures, a fact that irks many London Irish fans.
"I really enjoyed my time at London Irish. I gained a lot there and gave a lot back. I'm grateful for everything," Corbisiero told The Rugby Paper.
"There was a time when they were higher up the league and it was an exciting place to be, but being at the bottom of the league isn't ideal when you're looking to carry on developing, pushing and challenging yourself in top level situations.
"I just didn't think it was the right place to be any more."
Having decided to leave the Madejski Stadium, Northampton seemed to be the perfect fit for the New York-born player.
"Northampton are a great club with an awesome fanbase and a lot of history," he said.
"They're consistently in the top four of the league and playing in finals of the Premiership and Heineken Cup, and they've got a great group of young guys who, like myself, are playing for England and really want to kick on and achieve something.
"That was really attractive to me and the prospect of playing in that Northampton pack alongside Dylan Hartley and being coached by Dorian West makes it a great place to develop my game.
"My injury problems are behind me and I'm really looking to push on with them."
