A five-a-side football centre operator unveiled flotation plans yesterday that are expected to net a windfall for its bosses.

Powerleague is expected to have a value of about £40m - which is more than some Premiership teams are worth - when it lists on the Alternative Investment Market (AIM) next month.

The move should raise £12.5m and earn about £11m for the management team, including an estimated £7m for executive chairman Claude Littner - a former chief executive of Spurs.

Powerleague, which has 26 sites in the UK and has plans to open another 16, believes there could be scope for an additional 100 centres in the UK.

Mr Littner, who led a management buy-out from 3i Group in 2003, said he hoped the extra resources would enable Powerleague to develop more commercial deals, which have already brought tie-ups with Nike, Honda, Barclays and Carlsberg.

He said: ''We are breaking new ground in the five-a-side market, particularly in terms of developing commercial clients and attracting high profile sponsors."
