Lille lodged an official complaint, but Uefa refused it.
Giggs told Manchester Evening News: “The ref came over and said do you want the whistle, and I said no, I’ll take a quick one.
“So I said to Wayne, put the ball down, and that was it. I was pleased to see it go in, if it hadn’t I probably would have had a few words off the boss!
“Obviously I was pleased with the result, it was a somewhat contentious goal, but I’m obviously pleased with the points.
“But the last time I scored a goal like that, no one thought about walking off the pitch.
“I was just amazed by what was happening around us, we didn’t know what was going on, but that’s the French I suppose.”
