Statistics on Europa League/Conference League semi-finals of 18 May

*Three Italian clubs have qualified for the finals of the major UEFA club competitions (Inter in Champions League, Roma in Europa League, Fiorentina in Conference League). 
Last season with so many Italian clubs in the finals was 1997-98 (Juventus in UCL, Inter and Lazio in UEFA Cup).
Last season with an Italian club in the final of each of 3 different competitions was 1993-94 (Milan in UCL, Parma in Cup Winners’ Cup, Inter in UEFA Cup).

*Roma, with 0-0 in 2nd leg of UEL vs Bayer, have reached the final of a major UEFA European competition for the 2nd time in a row (also Conference Cup in 2022); as many finals as in the whole previous history of the club (1984 in European Cup, 1991 in UEFA Cup). 

*Sevilla have won 9 two-legged ties in the Europa League knockout stages out of 9 when they played at home in the 2nd leg.
With this 2-1 vs Juventus, they have won 24 of their last 27 games in the competition at home (drawing 2 and losing 1).

*Sevilla have qualified for their 7th final of UEFA Cup/Europa League. They won all 6 previous finals (2006, 2007, 2014, 2015, 2016, 2020).

*So, one of them will necessarily break their great unbeaten status in the European finals: Sevilla or Mourinho.

*Erik Lamela is the first Sevilla player to score in extra time at the Ramón Sánchez Pizjuan since 27 April 2006 when Antonio Puerta scored against Schalke in the UEFA Cup semi-final (1-0).

*Dušan Vlahović (Juventus) have played an away game of a European competition in Spain for the 2nd time. In both cases, he scored a fast goal : on 22 February 2022 vs Villarreal after 33 seconds (as a starter), now vs Sevilla after 61 seconds (as a substitute).

*West Ham (winning the 2nd leg of UECL semi-final vs AZ with 1-0 score) have reached the final of a major European competition (UECL) for the 3rd time in their history, after 1964-65 and 1975-76 (Cup Winners’ Cup in both cases); they won the first of these finals and lost the 2nd.

*Fiorentina have reached their 5th final in UEFA competitions (UECL); the last one was in UEFA Cup in 1989-90.

*Nicolás González became the 2nd player in Fiorentina history to score a brace in a semi-final of an UEFA competition (3-1 vs Basel), after Kurt Hamrin vs Újpest in Cup Winners' Cup in 1961-62.

*Fiorentina will take part in the final of a major UEFA competition and in the Coppa Italia final in the same season for the 2nd time in club history. 
The previous case came in 1961 (Cup Winners’ Cup, Coppa Italia) when they won both competitions.
