Manchester City winger Vladimir Weiss admits he upset Lubomir Moravcik by choosing to join Rangers over Celtic.
Weiss, 20, was chased by both halves of the Old Firm when Manchester City agreed to farm him out in the summer.
He said: "Lubo told me that both clubs are big clubs. Of course because he played there he wanted me to go to Celtic.
"But as soon as Rangers came in he knew the decision was down to me.
"I don't think he was happiest when I chose Rangers. But he is a friend so wherever I play he is going to support me and wish me luck."
