On 23 October 1991, in the first leg of an away UEFA Cup encounter against Swiss side Neuchâtel Xamax, Celtic lost 5–1 as Egyptian striker Hossam Hassan ran amok against the Celtic defence by scoring four goals, one of the worst European defeats in the club's history. In the return leg at Celtic Park, they could only manage a 1–0 victory and crashed out of the tournament 5–2 on aggregate. Celtic came third in the league in May 1992 behind Rangers and Hearts, lost to Airdrie on penalties in a League Cup quarter-final tie after a 0–0 draw, and were knocked out of the Scottish Cup by 10-man Rangers in the semi-finals.
