After suffering a miserable first Ryder Cup experience, Danny Willett believes his brother was correct in his criticism of American fans.
Danny Willett described his debut Ryder Cup as "s***" before backing up his brother's controversial comments describing American fans.
The Masters champion lost all three of his matches as the United States regained the trophy with a convincing 17-11 victory at Hazeltine.
Willett was well beaten 5 and 4 by Brooks Koepka in Sunday's singles, completing a miserable event, the build-up to which was overshadowed by his sibling's incendiary remarks.
Peter Willett described American fans as a "baying mob of imbeciles" and "pudgy, basement-dwelling irritants", leading Danny Willett to apologise on his brother's behalf.
In a media conference on Sunday, Willett was short and to the point when asked to describe his first Ryder Cup experience, before taking to Twitter on Monday to claim his brother had been proven correct after European players were subject to heckling and an overall hostile atmosphere throughout the three days.
"Very strange week here at the Ryder cup.. Tried my best but played poorly," he posted.
"Unfortunately some american fans showed that @P_J_Willett was in fact correct.
"Nothing to blame my bad play on.. But still shows that sometimes fans don't know when to call it a day.. Shame really!!"
