However, this year's European squad is said to be the 'strongest ever', featuring Florent Manaudou of France and Dutch swimmer Ranomi Kromowidjojo, both Olympic champions.
British Swimming head coach Bill Furniss is confident the 37-strong team, also including recent World Cup silver medallist
will be much more competitive.
"The European Allstars features by far the strongest line-up we've ever seen," he said.
"Both teams include a multitude of Olympic and world champions and medallists, and therefore the head-to-head promises to be a dramatic encounter."
