Russell Martin had insisted Rangers would work to "understand why and how we need to be better" during the international break, before being sacked.
The former Ibrox boss was dismissed on Sunday evening after the 1-1 draw with Falkirk.
However, before being removed from his position as manager, Martin had outlined his plans for the international break.
Martin planned to utilise the pause in domestic fixtures to train the lesser-used players in the squad as well as identify the issue plaguing a nightmare start to the season.
Rangers, who sit eighth in the league, have won just one match in the league this term, drawing five times and losing once.
Martin had earmarked the international break as an opportunity to reset, and hopefully capitalise on energy from players away on international duty in a bid to arrest the awful run of form the club were on.

Speaking to Rangers TV on his plans, Martin said: "It's time for work, especially for the guys who haven't played so much," he said.
"There are a lot of guys who go away on international who came back in with good energy after the last break because they done very well.
"We have to work really hard the guys who are here, and wait for the other guys to come back, and then get to work and understand why and how we need to be better."
A statement confirming Martin's exit read: "Rangers Football Club confirms that it has parted company with Head Coach, Russell Martin.
"While all transition periods require some time, results have not met the club's expectations.
"Assistant Head Coach, Matt Gill, and First-Team Coach, Mike Williamson, will also be departing.
"Russell and his staff have worked exceptionally hard throughout their time at the club. We thank them for their efforts and wish them well for the future.
"Further updates from the club will follow in due course."
