Successive England managers have complained about the impact of fatigue on their players at major championships and, with more foreign players calling the Premier League home, the former Manchester United star thinks it is time for change.
"When other countries are resting, the Premier League is at its most ferocious around Christmas when it's two or three days between games", said Giggs, who was in Shanghai to participate in the Tencent Super Penguin celebrity match on Saturday evening.
"Right from when I can remember, I used to go to Old Trafford and then, fast-forward to 17, 18, I played for the first team".
Giggs left Man United after 29 years at the club as a player, interim manager and assistant when Jose Mourinho was appointed boss in 2016 but remains an avid watcher and fan of his boyhood club.

It is not clear what either side is prepared to offer during the negotiations. Instead, the significance of dialogue with North Korea was emphasized.
"I was also a player who wanted to excite the crowd, to get the fans on their feet. That's what I tried to do when I was playing".
Giggs said he believes that having a strong core of players steeped in the club's tradition will be crucial as United bid to bring back the glory years.
"It was a really tight-knit group", he said.
"It always helps when you have the nucleus of players who know what the club's about or have been through the youth system".

" Nous croyons au G7 ", a répliqué Steven Mnuchin, en conférence de presse, au terme de la rencontre entre les ministres des Finances.
"They were special times because you're not only playing with teammates, you're playing with friends".
Manchester United legend Ryan Giggs believes Jose Mourinho's squad lacks players who are genuinely connected to the club.
"Football's changing, but you still have the likes of Rashford, Lingard, Pogba - who was there when he was younger".
"I think when it comes down to it, it shouldn't matter if you've looked after yourself during the season. It doesn't guarantee you success - and if you don't have that it doesn't mean you're not going to win - but it always helps if you do have that sort of team spirit".
