“It’s a fantastic group that awaits us in Slovakia. It’s going to be an amazing experience and we will be facing some of the best players on the planet.
“It is something that every one of us will embrace and this group of players has earned that right with the fantastic achievement in getting promotion last month.
“The hard work will start straight away and we have a lot of planning to do over the next 12 months.
“It is going to be an amazing year for British ice hockey and we will be going to Slovakia with the aim of continuing to surprise people again.
“We went to Budapest with two goals – one was to stay in the division and the other was to Dare to Dream. We now go to Slovakia with the exact same mindset and to enjoy this fantastic opportunity that has been created by our stunning promotion.”
