Manchester United are confident of topping their current AIG shirt sponsorship deal when it expires at the end of next season.

With AIG pledging to honour their four-year agreement, the situation is not quite as bleak as it was when Vodafone gave six months' notice of their intention to terminate in 2006.

Giant Indian corporation Sahara have already confirmed they are investigating United's proposals, while Saudi Telecom would also be among the companies who could be involved.

In addition, the Old Trafford outfit have strong links in both Malaysia and South Korea, so even at a time of financial prudence around the world, United are still optimistic of bettering a contract worth £19million including various financial packages.

"In line with industry practice, Manchester United is exploring the possibility of a shirt sponsor for the new 2010/11 season," said a United spokesman.

"The club is in dialogue with a select number of top companies worldwide and has so far received sufficient interest to be confident it can improve on its current £19million annual partnership with AIG."
