Conor McGregor took just 13 seconds to knock out Jose Aldo and become the UFC featherweight champion on Saturday.

The Irishman had talked the talk in the lead-up to UFC 194 and he delivered at the MGM Grand Garden Arena in Las Vegas.

McGregor's left-hook caught Aldo in the jaw and knocked him out, with the Brazilian landing one of his own as he fell.

With his win, McGregor improved to 19-2, while Aldo's record is now 25-2 after his first loss since November 2005.
