The best U17 and U19 water polo players in the country are set to take part in the biggest domestic competition of the season.
The 2015 ASA National Age Group Water Polo Championships takes place in Manchester this weekend with the top four teams in each age group battling it out.
The pick of the eight semi-finals could be in the Girls' U19 competition where North West rivals City of Manchester and City of Liverpool take each other on in a repeat of last year's final.
Many of the players will be teammates this summer after being named on the team for the 2015 European Games in Baku but there will be no love lost in the water on Saturday.
City of Manchester are the only team to have finalists in all four competitions while Exeter have qualified three teams for the Finals weekend for the first time in their history and look to have every chance in the Boys' U17 competition.
