Southampton are seeking new shirt sponsors over concerns regarding the future of LD Sports, it has been revealed.

The Daily Mail says Southampton have been left stunned as Chinese shirt sponsor LD Sports are set to quit the club before the new season - a shock decision that could cost the club £15million.

Club officials have discovered that the sponsor is likely to walk away from their agreement two years early.

The three-year deal, worth a club record £7.5million a year, started last season and was set to run until 2022.

Sources close to Southampton have admitted there was a break clause in the agreement this summer and that they are working to ensure they are not to be left without a sponsor going into the new season.
