New Rangers signing Kim Min-su says he brings a winning mentality and hopes to "help the team to be better every day". The South Korean winger, 20, has signed a four-year deal after joining from Girona for a reported £8.5m fee. Kim, who is Derek McInnes' 12th signing of the window, spent last season on loan at Spanish second-tier side Andorra where he made 40 appearances and scored six goals.
