TENNIS legend Andy Murray has taken to Twitter to slap down the President of the United States.

Following a suspected terror attack in New York city, Donald Trump took to Twitter to share his views, not on the incident, but on the New York Times.

Rather than wishing folk well or raising concerns over the bombing, Trump instead stated "Another false story, this time in the Failing @nytimes, that I watch 4-8 hours of television a day - Wrong! Also, I seldom, if ever, watch CNN or MSNBC, both of which I consider Fake News. I never watch Don Lemon, who I once called the “dumbest man on television!” Bad Reporting."

However, Olympic medal winning Andy Murray quickly spotted a glaring contradiction in Trump's tantrum tweet.

Quick off the mark he snapped back, asking "how do you know he’s so dumb if you never watch him?"

How indeed, Andy. How indeed.
