Robbie Henshaw has said that his desire to further his international career was one of the key reasons behind his switch from Connacht to Leinster.

The versatile centre has also voiced his annoyance in being forced to begin his career with the Blues on the sidelines after sustaining a knee injury during Ireland’s second-Test defeat to South Africa in June.

“It's pretty frustrating to start off in a new team being injured, but I'm making positive strides and its coming along according to plan,” Henshaw told RTÉ Radio 1’s Saturday Sport, in an interview which will be broadcast at 5.20pm this afternoon.

“The plan is to get back before the Europe stages, to be back for the Champions Cup in October.”

Of his move from Connacht at the end of last season, Henshaw said: "I wanted a new challenge and I wanted to try and work with the boys who I play internationally with.

"It was a tough decision, obviously, but I made it totally myself and it was for my career and hopefully it will benefit me in the long run."

The 23-year-old suffered the first major injury of his career just weeks after the double career high of Connacht’s historic Pro 12 final win in June, which was closely followed by Ireland’s first ever win over the Springboks in South Africa.

“Obviously finishing off with a trophy at the end of last season and then going to Cape Town to get a historic  win was the top of the rollercoaster,” he said.

“Then it all came crashing down in the second Test, which wasn't planned and was frustrating and killed me inside. I had to get the early flight home, which was annoying as well.

"But listen, that's what happens in sport and you just have to take it on the chin and get on with it.”

As well as a first run out for Leinster in October, the 23-year-old also has an eye on Ireland’s autumn Test fixtures – in particular the test match against world champions New Zealand in Chicago on 5 November.

“You want to be there and be involved in that first game over in Chicago,” he said. “It would be incredible for any player to be involved.”

Henshaw was speaking at the launch of Leinster’s new alternate jersey, which will be worn for the first time when Leinster take on Bath in a pre-season friendly in Donnybrook next Friday.

Leo Cullen’s side continue their pre-season build up with a friendly against Gloucester at Tallaght Stadium this afternoon (3pm).
