The Sky Blues have not won a game in this season’s addition of the competition, and look almost certain to drop out at the group stage for the third time since 2011.
City have won the Premier League twice over the course of the same campaigns, with their financial clout having brought success on the domestic front.
But unless they beat Bayern Munich this evening they have no chance of making a serious impact on the continent once again, and may have a struggle to finish third in their pool to get into the Europa League.
And Fortune feels that United would have put forward a much better account of themselves:
“This is their fourth straight season in the Champions League and they don’t seem to have learned anything at all,” he told Goal.com.
“United have not had a great start to the season but in that same group as City they would have done better, for sure.
“City have enough depth in their squad but they haven’t taken advantage of it. It’s hard to explain.
“United’s big plus is their experience. Wayne Rooney is a Champions League winner, so is Michael Carrick, so is Angel di Maria.
“And the manager knows all about winning the Champions League, too.
“The Champions League just isn’t the same without United. It’s like not having Barcelona or Real Madrid in it.”
