The mayor of Greater Manchester has called on Jose Mourinho and Pep Guardiola to support a plan to tackle widespread traffic congestion.
On Tuesday the Manchester United manager decided to get off his delayed team bus and walk to Old Trafford.
Andy Burnham has now asked Mourinho and Manchester City's Guardiola to use their "media presence" to strengthen his plans for a solution.
Road works in Regent Road have caused a raft of frustrating delays for drivers.
Widespread train cancellations and delays throughout 2018 have added to the problems for Manchester commuters.
Mr Burnham has ordered a review into travel surrounding week-night football games at Old Trafford, as part of his wider plans for a "long term solution" to the region's road and rail issues.
He said: "What I would want is for Jose to add his considerable media presence behind the campaign that I'm launching today.
"Nothing would please me more than Jose and Pep and whoever else might come to our aid and say this is a great city and it needs more support right now."
Manchester United was fined €15,000 (£13,203) by Uefa over a late kick-off caused by traffic delays in September.
On Tuesday the team stayed at a hotel half a mile away from the ground for its Champions League clash with Juventus but the bus journey took 45 minutes.
