Powell delighted with first start for Man Utd in friendly win
The new signing from Crewe Alexandra was shaken by a bone-jarring challenge involving Shouting Wang but continued before being withdrawn at the interval.
"I was fine," he told MUTV afterwards. "It was just a little jolt and my leg's okay. It did scare me but it's fine.
"It was great to get my first start and I want a bit more time to show people what I can do. It's a lot different to Crewe - they're in Swindon at an army camp and I'm coming here to China so it's ridiculous. I get on with most of them [team-mates] as they're a great bunch of lads and happy to be with them."
