Wayne Rooney's son Kai delights Man Utd fans

There is that tricky transitional moment in every father-son relationship when the younger man becomes the head of the family, steps up to the mantle and takes on the responsibility that comes with adulthood.

But Wayne Rooney was probably not expecting to be upstaged so soon by his five-year-old boy Kai.

As the 29-year-old Manchester United captain was signing autographs outside Old Trafford following the 1-1 draw with Arsenal on Sunday, he discovered he was no longer the centre of attention.

Witness Rooney Jr, in full kit, strutting his stuff like a seasoned pro and posing for photographs without breaking stride or sweat.

How long before Wayne is no longer the most famous Rooney in his own household?
