Shareholders repeatedly asked for details of the services the payment had procured, with the situation escalating to the point where Keswick was asked: "Is there a written contract or is it like (Michel) Platini and (Sepp) Blatter's verbal agreement?", which prompted an irate response.

Manager Arsene Wenger spoke of his legacy, saying he was determined to leave the club in such good health that his successor would be more successful.
"I am resolute and absolutely committed until the last day of my contract to bringing big success back to this club, as well to leaving the club in a position where it can do even better when I leave," he said.
"That is very important to me that I leave the club in the shape that the guy who comes after me can do better."
The Frenchman admitted that Arsenal must improve on the two FA Cups they have won since 2005, but added that he was proud to have qualified for the Champions League for 18 seasons in a row.
"Only one club in Europe, Real Madrid, has done better with 19.
"We want more and I am the first to agree that it is not enough. If it was easy everyone would have done it," he said.
