Rangers have extended the trial spell of former Dutch international Richard Witschge to allow manager Alex McLeish more time to assess his fitness.
Richard Witschge has had two spells with Ajax
McLeish has been impressed by the 34-year-old in training, but insists he needs more time to decide if he could improve the squad.
The former Ajax and Barcelona star spent last season playing in Japan.
"We'll have a behind-closed-doors game next week and we will have the chance to look at him then," said McLeish.
Left-sided Witschge won 31 caps for Holland, mainly as a holding player in the middle of the park.
"He is still training with us. He is still not at the same level of fitness as the rest of the players but we have been working him hard," added McLeish.
"He has mixed in really well and you can see that he is a gifted player in his passing and touch of the ball.
"Nothing has been decided yet. We will keep Richard here a bit longer - he has agreed to that - and he doesn't have to sign in a hurry to be able to play because he is a free agent.
"For the Champions League it is different. He would have to sign by the deadline of 31 August if he wanted to be involved in that.
"First I have to establish his fitness though. I don't like to commit myself until I am 100% sure."
