"I coached against them in 2000 and I thought they were massive then. If anything, in the last 13 years, they've become a bigger club on and off the field. It's unique, unprecedented, and unlikely to be matched again."
David Moyes also spoke about the quality of the A-League, saying: "There's no reason for Australian football not to become a major league itself.
"I know some of the Australian players from the past. Tim Cahill was one of my players. Obviously he’s not playing this game but I know their qualities.
"I also I know Lucas Neill from when he had a short spell at Everton. I’ll sure they’ll be up for the game. If you're picking the best from the A-League then we know it's going to be a big test for us."
