he received later in his career. Law scored a number of goals early in the 1963–64 season and was selected to play for a Rest of the World side against England at Wembley, scoring their goal in a 2–1 defeat. He later described this as the greatest honour of his career. His season was interrupted by a 28-day suspension for a sending off that he received against Aston Villa. The unusually cold winter forced United to play many of their fixtures in a short time, and their results suffered. Law later blamed this for United's failure to win a trophy in that season. Despite the lack of silverware, Law enjoyed a prolific goalscoring season and finished the campaign with 46 goals in all competitions, still a club record today. In 1964–65, Law won the Ballon d'Or award, and Manchester United won their first league title since Munich. Law's 28 league goals that season made him the First Division's top scorer. The following season, Law injured his right knee while playing for Scotland against Poland on 21 October 1965. He had previously had an operation on the same knee while at Huddersfield, and the injury was to trouble him for the rest of his career. In 1966, Law asked United's manager Matt Busby to give him a pay rise at his next contract renewal, and threatened to leave the club if he did not get one. Busby immediately placed Law on the transfer list, announcing that "no player will hold this club to ransom, no player". When Law went to see him, Busby pulled out a written apology for him to sign, showing it to the press once he had done so. Law later claimed that Busby had used the incident to warn other players not to do the same thing, but had secretly given him the pay rise. Despite all this, Law scored 23 goals in 36 league appearances during 1966–67, helping United win the league title again. In 1968, United won the European Cup for the first time, but Law's knee injury was causing him serious problems and he missed both the semi-final second leg and the final as a result. He was regularly given cortisone injections to ease the pain, but playing while the knee was still injured was causing long-term damage. He visited a specialist in January 1968 who wrote to United claiming that a previous operation
