Robert McNamara, 24, from Scarborough, North Yorkshire, has admitted attempting to enter as a trespasser, the striker’s family home in Prestbury, Cheshire, with intent to steal last August 3.
The alarm at the Manchester United and England star’s £6 million property was reportedly triggered at about 9pm and police descended to carry out a full search of the area.
Rooney, his wife, Coleen, and their three sons, Kai, Klay and Kit, were attending the charity tribute game at Old Trafford against his first club, Everton, when the break-in bid took place.
McNamara, of Newby Farm Crescent, Scalby, was arrested six days later and pleaded guilty at an earlier hearing at Chester Crown Court in October.
He had recently been diagnosed with bipolar disorder and his concerned family had sought help earlier this year from Combat Stress, a veterans’ mental health charity.
Judge Nicholas Woodward said there were “very worrying features” in the case and bailed McNamara while a pre-sentence report was carried out.
He will be sentenced later today at Chester Crown Court.
