Rangers needed to pick up all three points from their league game against City at the Etihad Stadium to maintain any chance of remaining in the English top flight for the 2015-16 campaign.
However, the London outfit failed, and failed miserably, as Argentina international striker Sergio Aguero destroyed them with a hat-trick.
Former Rangers forward Marsh is understandably disappointed to see the team go down to the Championship, but he wants the club to stick with Chris Ramsey and Les Ferdinand.
Ramsey was appointed the QPR manager until the end of the season following Harry Redknapp’s departure earlier this year. Ferdinand is the current director of football at the London outfit.
Yes, I was wrong! QPR are relegated. Must keep Ferdinand & Ramsey to rebuild.— Rodney Marsh (@RodneyMarsh10) May 10, 2015
