Steve Kean, manager of Blackburn Rovers, has been banned from driving for 18 months and fined £1,800 after he was convicted of getting behind the wheel under the influence of alcohol.
The 43-year-old, from Weybridge, Surrey, had earlier pleaded guilty to driving with excess alcohol at Macclesfield Magistrates' Court in Cheshire.
Although he applied to avoid the ban by claiming that his drink had been spiked, his plea was rejected by the judge, who said that Kean did not succeed in substantiating his claim.
Kean was nearly twice the legal limit when police stopped his black Mercedes on the southbound carriageway of the M6 near Knutsford, Cheshire, on May 14 and breathalysed him.
Blackburn played Manchester United in the Premier League on the same day.
Kean sped past a marked patrol car at 90mph, according to the prosecution.
