Batsman Aneurin Donald says his ambition to play for England was the driving force behind his move from Glamorgan to Hampshire.
The 21-year-old switched counties this week after signing a deal with Hants until the end of the 2020 season.
Donald wants to become the first Wales-born England player since Simon Jones in 2005.
"This will bring me closer to my goal of playing international cricket," said Donald.
"I am confident and feel as if I have the ability.
"This (Hampshire) is the best place for me to try and get on a Lions tour first and then move on to higher honours again as soon as possible.
"There are things I need to work on and things need to click but I feel as if I have it in me."
Glamorgan chief executive Hugh Morris said he was very disappointed Donald had turned down a new three-year contract offer, while head coach Robert Croft insisted they had done everything to keep him.
"It was a massive decision, one of the toughest things I have ever done," said Donald.
"As a proud Welshman and playing for the only Welsh county, it was not a decision I took lightly.
"I understand Glamorgan's disappointment and it has been a tough few months.
"I am grateful to all the opportunities Glamorgan have given me. I have so many people to thank over the years from Wales Under-11 cricket to the Glamorgan first team.
"It has been a tough year or two at Glamorgan. I wish them all the best and want them to do well and hopefully, one day, maybe I can even return."
Donald says the move to Hampshire was purely for cricketing reasons.
"It just came to the point where I needed a fresh challenge," said Donald.
"I was not desperate to leave, I just happened to come across a fantastic opportunity with Hampshire which I felt I could not turn down.
"I felt my game was stagnating at Glamorgan and this was a great opportunity to push my batting on in all three formats."
The former England Under-19 captain announced himself on the county stage in 2016 when he equalled the world record for the fastest first-class double century from 123 balls against Derbyshire at Colwyn Bay.
Donald has since struggled to build on this achievement and was dropped from Glamorgan's County Championship and 50-over sides but remained as a T20 opening batsman.
"My form has been up and down over the last couple of seasons," admitted Donald.
"I have had a couple of technical difficulties and it is about going back to basics.
"I am only 21 and have a long way to go. I made my Glamorgan debut at 17 and have played a lot of games for someone my age.
"Red ball cricket is an area I know I need to improve on. Hopefully I will have the chance to play first division in the County Championship if Hampshire stay up.
"First Division runs tend to be worth a little bit in the eyes of higher honours.
"I have favoured the T20 format and going to a team that has regularly won white ball cricket trophies is a massive draw."
