London: A look at what's happening in European football on Saturday:
Chelsea play Leicester in the FA Cup final at Wembley Stadium in the first of two huge matches between the clubs over the next four days. On Tuesday, they meet in the Premier League in what could end up being a playoff to secure one of the Champions League qualification spots.
The winner of the Cup final would gain a psychological edge. Chelsea are seeking to win their first trophy under Thomas Tuchel, who joined in January and has already got the team to the Champions League final taking place on 29 May, and the FA Cup final for the ninth time.
Leicester have never won the FA Cup and are seeking to capture a first trophy since improbably winning the Premier League in 2016. There are also three matches in the league, with West Ham aiming to stay alive in the race for a top-four finish by beating Brighton.
A win would leave West Ham in fifth, three points behind fourth-placed Chelsea. Southampton host already-relegated Fulham, and in-form Leeds travel to Burnley.
Antonio Conte's Inter Milan squad already ended Juventus' record run of nine straight Serie A titles. Now, Conte is looking to end his former team's chances of qualifying for the Champions League.
If Inter wins at Juventus, the Bianconeri may be mathematically eliminated from contention of finishing in the top four. There's a tight battle between four clubs for the remaining three spots, with Atalanta (75 points), AC Milan (75), Napoli (73) and Juventus (72).
Atalanta visit a Genoa squad with little to play for, while AC Milan (against Cagliari) and Napoli (against Fiorentina) play on Sunday. Lazio, who have 67 points but a game in hand, also still has an outside shot at the top four if it can beat Roma in the city derby ahead of its postponed game against Torino next Tuesday.
Cologne could be relegated from the Bundesliga for the sixth time if they lose at Hertha Berlin and other results conspire against them in the second to last round. Hertha are also not safe, but can clinch survival with a win.
Arminia Bielefeld, two points above Cologne, host Hoffenheim, and Werder Bremen visit Augsburg for another relegation battle. Bremen are ahead of Bielefeld only on goal difference, and Augsburg can still be caught.
Bayern Munich already have the title but Robert Lewandowski needs just one more goal to tie Bayern great Gerd Muller's record of 40 from the 1971-72 season. The Poland star's teammates have vowed to help him achieve it in Freiburg.
Freiburg can still qualify for the Conference League, Europe's new third-tier competition due to begin next season, by finishing seventh. Eintracht Frankfurt aims to pressure Borussia Dortmund in the last place for Champions League qualification with a win at already-relegated Schalke.
Bayer Leverkusen can clinch Europa League qualification with a win over Union Berlin, who are fighting Borussia Monchengladbach for the Conference League place. Gladbach, ahead of Union on goal difference, welcomes Stuttgart for Marco Rose's last game at home as coach.
