Giggs also discussed Donny van de Beek, who has struggled since his £40.5m move from Ajax this summer.
The Dutch midfielder has failed to break into the United first team in the league, and has only managed to play an hour of football from the bench in United’s first four games in the competition.
But Giggs insisted Van de Beek has still looked impressive during his limited opportunities for the side.
“I think with Van de Beek, it’s how does he get in the team?” he asked.
“When he’s come on, he’s impressed, he always looks like he’s got a goal in him. He scored for Holland during the international break.”
