Australian full-back Shannon McDonnell says he is ready to face his old team-mates in the Hull derby on Sunday.
The 25-year-old spent his first season in Super League with Hull KR but, after being unable to agree a new deal, he switched to arch-rivals Hull FC, signing a two-year deal.
Along with former Rovers captain Ben Galea, McDonnell will face an early reunion with his old club when they meet in a pre-season friendly at the KC Stadium this weekend.
"It's a part of league," he said. "Players move teams. It's a bit different here with two teams in the same town but all my focus and energy is with FC now."
McDonnell, who played the first 21 matches of 2012 before suffering a knee injury that called time on his season, had resigned himself to returning to Australia when talks collapsed with Rovers.
"I enjoyed my time at Craven Park," he said. "It's a good club and the fans are really passionate and loyal. It was a good place to be.
"The negotiations just didn't work out the way we hoped and there was an opportunity that came up with FC late in the season."
McDonnell is one of seven new faces at the KC Stadium, and he is delighted with the competition for places.
"You don't really want to put much expectation on where you want to finish and what you want to achieve at the start of the season," he said.
"We're a new team and we're just excited to all play together and start gelling, with all the new faces that are here.
"There's a real good depth with all the halves we have, with their experience and knowledge. I think it's a good problem for the coaching staff to have in picking the halves."
