Striker Cedric Itten admits he was disappointed not to be given more game time before being shipped out on loan.
The Swiss frontman joined Greuther Furth on a season long loan deal on deadline day and scored on his first appearance in a friendly win.
There is an option to buy for the German side although Rangers can recall him in January if they decide they need him for the second half of the campaign.
However, the 24-year-old may not be keen on a quick-fire return to the Premiership champions.
Itten has told Kicker he was frustrated at the lack of minutes during his season at Ibrox, having signed last summer from St Gallen.

He reckons the lack of big name transfer exits from Steven Gerrard 's side has impacted on his chances so far.
Itten told the German media: "I wish I could have played more there but we had a big squad that was largely together for three years without notable departures.
"It wasn’t easy to play yourself into the side.
"I benefitted from being in a new country and from a different type of football.
"Steven Gerrard is definitely a big personality. He is very well equipped tactically and I was able to learn a lot."
Itten reckons he will come back to Glasgow a better player after signing with the Bundesliga new boys.
He went on: "I think that in Furth I will find exactly the conditions to develop myself as best as possible.
"With the impressions from the conversations and what I have already heard about Furth, it was my absolute wish to come to Furth."
