The Reds have spent the last week working on fitness in Sydney ahead of Saturday's clash at the ANZ Stadium and Yorke, who spent time as a player with Sydney FC, is expecting the Aussies to put up a decent fight.
"It will be a good team from the A League – they will have good quality," he told ManUtd.com. "They have selected the top players in the league and that gives them a better chance in terms of competing with the players. We know this is work in progress for the lads, but it'll definitely be a good run-out.
"Of course, the quality of football over here isn't the same as the Premier League, but it's a sport that is growing all the time. Playing in Sydney was a great experience for me. It's a great place to be and I thoroughly enjoyed my time out here."
