Rangers have taken former Germany international winger David Odonkor on trial.
Odonkor, 27, is a free agent after leaving Real Betis, who he joined in 2006. He flew into Glasgow on Wednesday and will spend ''the next few days'' training at Murray Park, the club announced on their website.
Odonkor endured a largely miserable spell in Spain, making just 52 appearances in five years for Betis amid a series of knee injuries.
The right-sided player did not play at all last season but he has come to Glasgow determined to prove his fitness.
Odonkor, who is known for his pace, broke into Borussia Dortmund's first team aged 18 and played for his country at the 2006 World Cup and in Euro 2008.
The most recent of his 16 appearances for the national team came in the latter tournament.
Odonkor is hoping to become the club's fourth summer signing after Rangers brought in Spanish winger Juan Manuel Ortiz, Scotland left-back Lee Wallace and Romania defender Dorin Goian.
United States winger Alejandro Bedoya has signed a pre-contract agreement and is due to join from Swedish side Orebro in January.
Rangers have also had bids for Dundee United striker David Goodwillie rejected with the Tannadice club holding out for the £2million asking price amid interest from England.
Manager Ally McCoist has also been linked with a move for Anderlecht's Hungary defender Roland Juhasz and ADO Den Haag's Wesley Verhoek.
But reports claim Den Haag want £2.7m for the winger with Rangers only prepared to offer £1m for a player who has a year left on his contract.
