A Rangers source is claimed by the Echo to have said
"Walter (Smith) is a big admirer of Loovens and has watched him for some time.
"He believes Loovens would fit in well at Rangers and as he only has two centre backs on his books, is keen to sign a new man in time for the Champions League qualifiers."
It's thought that Rangers want £800,000 - £1m in cash plus Glenn Loovens to trigger a move to Cardiff for Boyd. But City value Glenn more than that.
