Worthington was impressed with McGinn’s performance on his debut for Northern Ireland in the goalless draw against Czech Republic in Prague.
“I thought little Niall McGinn was fantastic,” Worthington said. “He was a breath of fresh air for us. His running at the Czech defence caused them all sorts of problems.
“It is terrific to have him on board. I wasn’t at all surprised at his impact on the game because I am well aware of what he is capable of. He has been around the squad throughout the campaign.”
