Europe's players celebrated a knee-knocking 15-13 Ryder Cup victory over the United States in New York by trolling Donald Trump. "Are you watching Donald Trump," sang the victorious players in response to Rory McIlroy receiving a text message from the US president, who is a well-known golf fan. And Trump, who made a brief appearance at the Bethpage Black course on Saturday, took it well, writing on social media: "Yes, I'm watching. McIlroy has played golf with Trump and last week spoke about his affinity for the United States. Irishman Lowry, a good friend of McIlroy's is stood in the middle of the coach screaming "he's in your head, he's in your head, Rory, Rory, Rory..." to the tune of the 1990s Cranberries song 'Zombie'.
