Liverpool won the championship again that season, but the arrival of Israeli international striker Ronny Rosenthal saw his first-team opportunities limited in the title run-in, in which Liverpool overcame a strong challenge by Aston Villa to finish champions by a nine-point margin. Despite UEFA lifting the ban on English clubs in European competitions for the 1990–91 season, Liverpool were unable to compete in the European Cup as (being the team present at the Heysel disaster that had sparked the ban in 1985) they had to serve an extra year of the ban before being allowed to play in European competitions again.
