Former Celtic star John Hartson revealed that he immediately rebuffed Sir David Murray when the Rangers owner tried to entice him to Ibrox 15 months ago.

The Welshman failed a medical at Rangers when Dick Advocaat was manager and he subsequently signed for Celtic where he became a fans´ favourite under Martin O´Neill, but during Paul Le Guen´s ill-fated tenure at Ibrox, Murray tried to persuade Hartson to leave West Brom for what would have been a sensational return to Glasgow.

But the former Wales international claims Murray´s phone call was a waste of time, saying in the Scottish Sun: "There was no way that I could ever pull on a Rangers shirt after all that I achieved in five years at Celtic."
