* Senior club appearances and goals counted for the domestic league only.
He scored twice in the final as Rangers defeated Dynamo Moscow 3–2 in Barcelona. In December 1972 he moved to England to join West Bromwich Albion, making his debut against Liverpool in the same month. Albion paid a club record £138,000 to bring him to The Hawthorns.
However, his career included some controversial incidents. After Scotland's opening game of the 1978 World Cup, against Peru, Johnston tested positive for a banned stimulant contained in Reactivan, a medication prescribed for his hay-fever. His subsequent expulsion from the squad ended his international career after 21 appearances, although he maintained his innocence.
While playing for the Vancouver Whitecaps, he once mooned the Seattle Sounders bench following a goal, and on another occasion took a swig from a fan-offered beer before taking a corner kick in San Jose, setting up a goal from the set-piece. Johnston was a key member of the 1979 NASL champion Vancouver Whitecaps, helping them defeat the New York Cosmos in the semi-final, and then the Tampa Bay Rowdies 2–1 in Soccer Bowl '79.
Aberdeen player John McMaster had to be given the kiss of life during a game against Rangers at Ibrox in 1980 after Johnston stamped on his throat. Johnston later 'justified' his action by saying he thought it was Willie Miller.
In 2004 Johnston was named as one of West Bromwich Albion's 16 greatest players, in a poll organised as part of the club's 125th anniversary celebrations.
Johnston now lives in Kirkcaldy. The Port Brae Bar pub in Kirkcaldy was run by his son Dean until a dispute with the Belhaven Brewery led to the pub being boarded up, locking Johnston's collection of memorabilia inside.
