 Hearts chairman Wallace Mercer apologised to Walters.Whilst at Ibrox, Walters was part of the side that won the Scottish Premier Division in 1989, 1990 and 1991 and the Scottish League Cup in 1988 and 1990, thus enjoying the most successful spell of his career in terms of trophies won.Liverpool paid £1.25 million for Walters' services and he made his debut four days after signing, when he came on as a 65th-minute substitute for Steve McMahon in a 2–1 league win over Oldham Athletic at Anfield on 17 August 1991.
