A look at what's happening in European football on Wednesday:
Already in the League Cup final and with a commanding lead in the Premier League, Manchester City could be headed for another domestic treble as Pep Guardiola's team switches focus to the FA Cup and a fifth-round trip to second-tier Swansea.
A victory at the Liberty Stadium would be City's 15th straight in all competitions and break the record for the longest winning run by a top-flight English side, surpassing Preston (from 1892) and Arsenal (from 1987).
Swansea are one of the in-form teams in the Championship, though, having beaten leader Norwich last weekend to extend their undefeated run to eight games and close in on the automatic promotion spots. There are two all-Premier League matchups as Everton host Tottenham and Brighton visit Leicester, while Sheffield United are at home to second-tier Bristol City.
With both teams peaking, Barcelona visit Sevilla in the first leg of the Copa del Rey semi-finals. The Catalan club enters the semis coming off a six-game winning streak in all competitions, while Sevilla have won seven in a row in all tournaments. The teams played in the Copa final in 2016 and 2018, with Barcelona coming out on top both times.
Lionel Messi is set to start for Barcelona after being rested during part of the team's Spanish league win over Real Betis on Sunday. Coach Ronald Koeman will be without three players because of injuries " Martin Braithwaite, SergiÃ±o Dest and Miralem Pjanic. Sevilla's Julen Lopetegui will be without injured players Lucas Ocampos and JesÃºs Navas.
Athletic Bilbao host Levante on Thursday in the first leg of the other semi-final.
Holder Napoli visit Atalanta in the second leg of their Italian Cup semi-final. The winner will play Juventus in the final on 19 May.
Napoli beat Juventus last season to win their sixth Italian Cup trophy. Atalanta have reached the final on four occasions, and as recently as 2019, but their only triumph in the competition was in 1963. Both Atalanta and Napoli have yet to win a match this month.
Mauricio Pochettino's PSG side has been hit by injuries to several key players ahead of Wednesday's trip to second-division club Caen in the French Cup's round of 64. Before traveling next week to Barcelona in the Champions League, Pochettino is expected to rotate his squad as PSG starts the defense of their title in Normandy without Marco Verratti and Angel Di Maria.
Following their 2-0 loss to PSG in the French league, 10-time French Cup winner Marseille play at Auxerre without their new striker Arkadiusz Milik, who is sidelined with a thigh injury and should not return before next week. Midfielder Olivier Ntcham, whose arrival on loan at the southern club on transfer deadline day triggered coach Andre Villas-Boas' departure, is expected to make his debut.
