The Sky Blues fell to defeat in their latest Professional Development League South clash, when they were beaten by Colchester United.
City Under-23s lost 4-2 away at Florence Park, despite taking the lead in the game early on, when Jordan Ponticelli headed home from a Dion Kelly-Evans cross.
It was the Sky Blues first defeat in four games and they remain within touching distance of top of the league.
QPR are just a point ahead of City, as they are level on points with Crystal Palace in second place.
Reflecting on the game, Under-23s coach, Jason Farndon admitted he was disappointed with the way his side suffered the defeat.
He said: “It was a disappointing result.
“The team was much changed to previous weeks and we had a few first team players and I just thought we thought that we didn’t really get going.
“The shape didn’t work. We changed at half time and we became a little bit better, but I just don’t think there was enough energy and enough life around the way we passed the ball and the way we worked to get the ball back.
“It was just a really disappointing day after a long trip top Colchester.”
The Sky Blues pushed in the second half to try and fightback, but a goal from Bilal Sayoud wasn’t enough, as United secured all three points.
The league remains relatively tight at the moment, with just five points separating sixth position and first and just the one point separating City with first.
Jason believes despite the league competition, the under-23s is about developing players, however looking at the table and wanting to win the league also helps.
He added: We look at the league table because I think it’s a good habit for young players to have to try and win that league and I think that will bring a new dimension to their game.
“However, it is a development league and we are looking for different outcomes and the disappointing thing with that game was that we didn’t get the result; we didn’t get the development because we weren’t good enough in the game.”
