“I came here full of self-belief,” he told the club’s media.
“I’m an attacking player who creates lots of chances. I’m direct and I score goals—that’s what matters most.”
“I’m here to win trophies and become a winner with Rangers. I want to help the team improve every day, be a good person, and do everything I can to help us win whatever comes our way.”
“I’m really excited and I believe I have a winner’s mentality. I want to meet whatever comes next head-on and give the club what it deserves.”
The Ibrox side have been pursuing wingers, with Minsu joining Djeidi Gassama, Findlay Curtis and Ross McCausland, plus fellow summer arrival Daisuke Yokota.
Rangers were close to signing PSV Eindhoven’s Couhaib Driouech earlier this month, but the 24-year-old was carrying a minor injury.
Brighton then rejected a £7.5m bid from Ibrox for 21-year-old Amario Cozier-Duberry.
“Enhancing our attacking options has been a major aim this window, and we believe he’ll bring an exciting new dimension to the squad,” manager Derek McInnes said of his new winger, who will wear the number 10 shirt.
“Minsu is a highly talented young player with excellent technique, energy, and a real hunger to develop, and we’re looking forward to working with him.”
