Manchester Utd's plans to celebrate their 19th league title and, possibly, a third European Cup are "exhausting" and will seriously effect preparations for next season.
Manager Sir Alex Ferguson is reportedly horrified by the club's plans to celebrate over the summer.
Said a club spokesman: "The celebrations are going to be huge and very long-running.
"The trouble is, as everybody knows, our fans are not concentrated in Manchester, like City's. Ours tend to be glory-seeking residents of other provincial towns and cities with less glamorous clubs.
"This means we have to book open-top bus tours throughout the country and even in the Republic of Ireland. For example, over three consecutive days in June we're scheduled to be in Worcester, Belfast and Dublin.
"There's even talk of foreign visits - we're very popular abroad.
"Sir Alex is not happy with the arrangements at all - he fears they will exhaust his players and wreck his pre-season plans for the Caribbean holidays."
