The only way that we would need to increase the capacity of the stadium would be if we were to get to the Premier League. Arsenal have found out the hard way that a stadium no longer draws the revenue that enables teams to compete. It is actually restrictive if clubs need to draw back to fund stadium development and additional resource allocation.
The main source of income for Premier League clubs is TV revenue given the competition between Sky, BT and even Amazon.
Should we reach the promised land, a modest extension (of 3,000) to placate the armchair fans would surely suffice?
