(CNN) — Goalkeeper Adrian’s Liverpool career is proving a serious roller coaster. The Spanish shot-stopper only joined the club on August 5 to provide cover for Alisson Becker, but was immediately thrown in at the deep end after the Brazilian keeper lasted a calf injury in Liverpool’s opening afternoon Premier League victory over Norwich. In his second match for the Reds, Adrian proved to be protagonist as Liverpool beat Chelsea on penalties to win the UEFA Super Cup final on Wednesday. However, since the Liverpool players thronged around Adrian to congratulate him on his match-winning penalty save to thwart Tammy Abraham, a supporter hurried from the racks to join in the parties and managed to injure the goalkeeper’s ankle from the melee.
