The 1990–91 season would be Souness's last season in charge. On 16 April 1991, the fiery Scot departed for his former club Liverpool before the league campaign reached its dramatic culmination, saying he had "gone as far as he would be allowed to go". A last-day victory over Aberdeen at Ibrox gave Rangers "Three in a Row". Souness assistant Walter Smith was in charge that day. Before his departure Souness had made sure to fall out with and sell on club captain Terry Butcher and spend big money on striker Mark Hateley, winger Pieter Huistra and forgotten man Oleg Kuznetsov. Sadly for Souness though he was never to win a Scottish Cup with Rangers as the team went down 2–0 to Celtic at Parkhead, for the second season in a row. The 1990 Scottish League Cup Final ended in another victory, however.
