Rangers have bolstered their wide options with the arrival of Kim Min-su from Girona for an undisclosed fee, with manager Derek McInnes saying the South Korean adds “another exciting dimension to the squad”.

The 20-year-old has signed a four-year contract, with the option of a further year, becoming Rangers’ 12th signing of the summer.

Kim was loaned to second-tier Andorra last term and leaves Girona after their relegation from La Liga. He scored 19 goals in 84 appearances for Girona B and played eight times for their senior team. At Andorra, he netted six times in 40 games and provided four assists.

And he admits “it was a surprise” to hear of Rangers’ interest.

“I have a lot of confidence in myself to come here,” he told club media.

“I am an attacking player and I make many chances. I am direct and score goals – this is the most important thing.

“I’m here to win titles and to become a winner with Rangers. I want to help the team to be better every day, to be a good person and to do everything I can to help the team win everything that comes our way.

“I have a lot of excitement and I believe I have the mentality of a winner. I want to face whatever comes next head-on and I’m going to give the club what it deserves.”

The Ibrox outfit have been chasing new wingers, with Minsu joining Djeidi Gassama, Findlay Curtis and Ross McCausland, as well as another summer recruit in Daisuke Yokota.

Rangers had been poised to buy PSV Eindhoven’s Couhaib Driouech earlier this month, but the 24-year-old had been carrying a minor injury.

Brighton then rejected a £7.5m offer from Ibrox for Amario Cozier-Duberry, 21.

“Strengthening our options in the forward areas has been a real target and focus for us throughout this window and we believe he will add another exciting dimension to the squad,” manager Derek McInnes said of his new winger, who will wear the 10 jersey.

“Minsu is a talented young player with excellent technical ability, energy and a real desire to develop and we are looking forward to working with him.”
