Under siege Fiji have re-hired former national sevens coach Ratu Kitione Tuibua in an attempt to revive the team's fortunes before the all-important Hong Kong leg of the IRB World Sevens Series next month. Tuibua, who coached Fiji to a memorable hat-trick of wins at the Hong Kong Sevens from 1990 to 1992, has replaced Alifereti Cawanibuka as Fiji's coach for the remainder of this year's International Rugby Board sevens calendar. The genial Tuibua, who apart from his coaching background is also a spiritual chief, will have a tough task on his hands in lifting the morale of Fiji, who are currently languishing in the unaccustomed position of fourth on the World Sevens Series standings with 50 points, 30 adrift of leaders New Zealand (80). South Africa (72) and Samoa (56) are also ahead of Fiji. 'It's not going to be easy but I need to talk to the players. I believe something is wrong, but I can't put my finger on it yet,' Tuibua told Fiji Rugby Web site Teivovo.com. Fiji had a forgettable season last year when they lost their Sevens Rugby World Cup crown to arch-rivals New Zealand and failed to win even one leg of the World Sevens Series. The ignominy of defeat on the pitch was increased by the one-year ban imposed by the IRB on last year's coach, Tomasi Cama, for manhandling a match official at the Kuala Lumpur Sevens. Cama was replaced by Cawanibuka. The once giants of sevens rugby have continued to struggle this year too, winning only one of the five legs of the Series - in Argentina - despite the return of Waisale Serevi into the fold. Cama dropped Serevi last year on the grounds of poor form and fitness. Fiji plumbed new depths earlier this month at the Wellington Sevens when they were knocked out of the Cup competition by England, losing 19-14, and then failing to reach the Plate finals after going down 21-12 to Argentina in the semis. Tuibua believes that more input is needed from officials and players to lift Fiji back to their glory days. He noted that the Fiji players appeared to be unhappy. 'If they were happy, they would give their best and play with a happy heart. Things like that only come down to team management,' Tuibua said. Tuibua's comeback could see the return of some old faces to Hong Kong, including veteran Samisoni Rabaka and little master Serevi, who has won his place back in the team. Tuibua's first tournament back at the helm will be the March 16-17 Beijing Sevens, a week before the Hong Kong leg. The draw for the Hong Kong Sevens will take place next Tuesday. Fiji will need good results at the remaining six legs, including a victory in Hong Kong which offers more points, if they are to stand a chance of winning their first World Sevens Series title and preventing New Zealand from making it a hat-trick. The sevens mad country can only pray that Tuibua will provide the team with the inspiration to achieve this.
