These are Tottenham (22 April, but subject to change) and Wigan (7 May).
This facility is similar to that suggested previously by AISA for big matches. There will obviously be enormous demand for these two matches, and the Club describe this facility as being "to reward Members who have most regularly attended home matches this season." More information from the site:
In order to apply for tickets for these final two Premiership matches at Highbury, Silver Members will be required to have attended a minimum number of home matches during the current 2005/06 season (the number has not yet been announced).
