Les Gones had to deal with the departure of Michel Bastos, who moved on loan Schalke, with the French club's attempts at finding a replacement falling short.
Garde though is hopeful that his players can refocus on playing football now that the unsettling month of January is over, starting with Sunday's clash at Ajaccio.
"The transfer window does not create good working conditions," he said on www.olweb.fr. "Players are always a little disturbed. We have lost Michel and have not strengthened, but a page has been turned.
"I now want to work and grow with this squad, there are many young players.
"I hope they are aware there are two great challenges facing us over the next four months: Ligue 1 and the Europa League.
"Our first priority is Ajaccio. Like all away games it will be complicated and difficult."
