Rangers and Aberdeen exchanged two players ahead of the transfer deadline with Richard Foster moving to Ibrox in place of Andrius Velicka. Foster joins Rangers on a season-long loan with Velicka moving in the opposite direction for the same period.
Foster admitted he was going to Ibrox as a squad player but the 25-year-old is excited by the prospect of playing in the Champions League.
Foster, who has made 250 appearances for Aberdeen, told www.rangers.co.uk: "It has all happened very quickly. I was surprised the way things have gone and I'm very excited by it.
"The Champions League is the biggest stage of all and to have a chance of playing there is terrific.
"You look at the teams in the group and it's going to be brilliant.
"I have never been to a Champions League match at Ibrox but having watched on TV you can see that the atmosphere is incredible so it's something that I would love to be involved in.
"This is a really good opportunity for me. I am under no illusions that I am going to walk into the team but I will work really hard to try to get there and if I do it will be a great personal achievement.
"So I have to hit the ground running and show what I can do in training and try to get into the manager's plans as early as I can.
"If you look at the Rangers team it's going to be difficult for me to break in. Hopefully my pace can be an asset in either of the full back positions or further forward.
"I realise that I am a squad player but I hope to do what I can to show that I can play for Rangers."
