On Sunday he was once again forced on to the sidelines because of a build up of fluid in his knee and he could play no part in his side's 3-2 cup win at Ross County.

The Scottish Cup is now the champions' only realistic chance of silverware this season and their other main goal is to finish second, ahead of Hibernian, in the Scottish Premier League.

Mols has not started a game since the winter break finished and revealed that he had overdone it on the trip to Florida.

He told Rangers News: "The fluid is there in my knee but the strange thing is that doesn't bother me when I am playing.

"I played against Dunfermline and Celtic and there was no problem at all. I feel no pain. The only thing that will get rid of it is exercise, ice and, most importantly, no irritation.

"I must get back to full fitness but I must not go too far this time or it could set me back again.

"Florida was the problem, the step was too big. I was doing practically nothing before we left, then in the States I was taking part in two training sessions a day. That's the reason fluid returned.

"I have struggled all season - just like the team. The entire squad has found it difficult with injuries and form. My aim is to return playing regularly at a normal level for the rest of the season.

"Recently I said I'd be back to my best in three weeks. But when I said that this latest setback wasn't in my mind. I find it strange because I am a lot happier football-wise now than I was before the winter break. At that time, before we went away, I was struggling with my form.

"Now I have confidence and am feeling very good about myself, particularly after playing okay in the win over Dunfermline a couple of weeks ago. The terrible thing is I can't show it at the moment. This entire year has been frustrating."
