Europe's Danny Willett has tweeted that his brother Peter was correct in his pre-Ryder Cup criticism of American supporters.

Willett's brother had described the fans as a "baying mob of imbeciles".

The Masters champion, 29, had a poor Ryder Cup debut, failing to win a point as Europe lost 17-11.

"Tried my best but played poorly," he said. "Unfortunately some American fans showed that @P_J_Willett was in fact correct."
