London, May 7: The second leg of Liverpool's clash with Barcelona takes place on Tuesday, with the Spanish side on the verge of the Champions League final following a 3-0 victory at Camp Nou in the first leg.
Lionel Messi was the star of the show on that occasion, scoring twice - one a spectacular free kick - to add to Luis Suarez's opener against his former side.
Liverpool's task of turning the tie around is made all the harder by injuries. Jurgen Klopp confirmed that forward duo Roberto Firmino and Mohamed Salah will both miss the tie, while midfielder Naby Keita is ruled out after picking up an injury during the defeat in Spain.
Either Ajax or Tottenham will be the opponents in the final, with the Dutch side holding a 1-0 first-leg lead. Ahead of the game at Anfield, we pick out the best Opta facts.

3 – Only on three previous occasions has a team been eliminated from a Champions League knockout tie having won the first leg by three or more goals. The last occasion it happened involved Barcelona last season, who won 4-1 at home against Roma but then lost 3-0 in the return fixture of the quarter-final clash.
