Speaking about the meeting, he told Daybreak: "It was one of the best moments of my life. I had such a busy week and I arrive at the White House to meet the President and the First Lady, and he gives me a lot of stick and gives my underwear a plug; it was perfect."
Referring to his week which included a football match in California and joining Lord Coe for an Olympics hand-over in Athens, he said: "It was one of the busiest and best weeks of my career and life."
