Martin Kaymer (right) beats 2020 US Ryder Cup captain Steve Stricker to seal Europe's victory at Medinah in 2012 – the only road victory in the past seven editions
The Ryder Cup can be played in neutral locations to limit home advantage , says Captain Padraig Harrington.
Six of the last seven editions have been won by the home team.
Harrington, 48, played in six Ryder Cups and will lead Europe next year against the US for Whistling Straits, Wisconsin.
"Forty, 50 years later, it is probably best to have a neutral attitude," said the triple Irish winner.
"Then there is no golf course like we did in Europe (at Le Golf National), so it was very tight off the tee and par was a very good score.
" If you went back to Hazeltine, it was more of a birdie fest. "
Since the" miracle of Medinah "in 2012 when Europe came from 10-4 to the US beat 14.5-13.5, the Ryder Cups were all comfortable home victories.
Europe won 16.5-11.5 at Gleneagles in 2014, the US triumphed 17-11 in Hazeltine, Minnesota, in 2016, and Thomas Bjorn & # 39; s team triumphed 17.5-10.5 at Le Golf National in France last year.
Home captains can set up courses that match their players.
But Harrington, speaking at an event to mark another year before the Ryder Cup 2020, said Whistling Straits, on the shores of Lake Michigan, not so easy to change for the American Captain Steve Stricker.
"This is a much more natural course," Harrington said. "I'm interested to see what Steve has in store along the way, but it doesn't look like you can do much with this golf course.
"It looks like it is in a natural environment and the weather can be very changeable in the week of the Ryder Cup.
" This is a golf course that the players use on their own test. "
The 2020 Ryder Cup will take place from September 25 to 27, with television highlights and radio commentary on the BBC.
