The competition allows the home team captain to dictate the course setup to favour his players and Harrington, whose squad will face the United States at Whistling Straits next September, feels there can sometimes be too much of an edge.

"In Europe, we get to set the golf course up and we set it up every way we can to suit our players.

"And in the States, we've seen that, as well, where the golf courses are set up to be most advantageous for the home team," Harrington told a news conference at Whistling Straits alongside US counterpart Steve Stricker.

"It's obviously not going to happen probably in my lifetime, but 40, 50 years down the road when the Ryder Cup is still going along, it will probably be best to have a neutral setup."

Harrington was a vice captain at the 2018 Ryder Cup where a challenging Le Golf National course setup proved to be one of Europe's biggest weapons as they enjoyed a 17.5-10.5 romp in Paris.

It was a stark contrast from the 2016 Ryder Cup at Hazeltine National in Minneapolis, where wide fairways, little rough and routine pin positions drew plenty of scorn from the defeated European side.

But Irishman Harrington said he does not feel Stricker will be able to do much to make the European side feel uncomfortable on the rugged and windswept links-style Whistling Straits course that runs along Lake Michigan.

"This is a much more natural golf course. I'm interested to see down the road what Steve has in store but doesn't look like you can do a lot with this golf course," said three-time major winner Harrington.
