Rangers have announced the signing of defender Mateusz Zukowski from Legia Gdansk.
The right-back arrives at Ibrox after the clubs agreed an undisclosed fee, and Zukowski has signed a three-and-a-half year deal.
The 20-year-old arrives as a replacement for Nathan Patterson, who left for Everton earlier in the window, and will be back-up for club captain James Tavernier in the right-back position.
Rangers manager Giovanni van Bronckhorst believes the club have signed a young player with the potential to develop.
“I am really pleased that we have been able to add Mateusz to our squad,” Van Bronckhorst told the club website.
“We knew when Nathan left at the start of the month that we would need cover in the right full-back area, and it is great we have been able to find someone of Mateusz’ quality.
“He will be able to learn so much from our captain and I hope to see him develop further as a player here at Rangers.”
Zukowski said: “I am delighted to join Rangers and to make this next step in my career.
“I have been so impressed with everything I have seen and heard about Rangers and to join a club of this size is fantastic for me.
“I look forward to meeting my teammates and to making my debut in front of the supporters as soon as I can.”
Rangers sporting director Ross Wilson added: “As part of our transfer strategy this window we wanted to recruit a young, right full-back who we see high potential in to further develop.
“Mateusz absolutely fits the profile that we were looking for in the market and we are all looking forward to working with him. He is a determined character and I know how excited he is to come here.
“Our scouting network in Europe have tracked him intently and we are pleased that Mateusz has now become a Rangers player today.”
