I don't know if there was a central pot that was divvied out to all football locations or it was based on ticket receipts, either way, ACL are probably less concerned about their current tenants than previously...
"It also seems United pocketed around £2million as a result of Old Trafford being an Olympic venue given a 13.3% rise in matchday revenue to £19.6million."
Whatever it was I expect it has certainly helped the recent cash-flow of ACL so would have helped this year for sure.. perhaps this is allowing them to be more lenient with the club over the rent in the short term
