Should the St Mary s stadium be extended? FINANCIAL experts agree that extending Saints St Mary s stadium would be a risk without the certainty of regular sell-out crowds. There are currently 21,000 season ticket holders, but chairman Rupert Lowe says the board would only consider extending the ground if they could be confident fans would regularly fill the spare seats. Southampton Deloitte & Touche partner Stuart Woodward said: By spending millions on making thousands of extra seats available, you run the risk of not being able to fill the ground to capacity. It s better to be in a position where demand just outstrips supply - better to have the ground full every week with people wanting to get in than lots of empty seats.
