The Semi-Final Bracket and How Each Club Got Here
The Champions League semi finals open with Paris vs Bayern at the Parc des Princes on Tuesday 28 April, followed by Atleti vs Arsenal at the Estadio Metropolitano on Wednesday 29 April. Paris and Bayern arrive as attacking juggernauts, each scoring 38 goals in this season’s competition and eliminating Liverpool and Real Madrid respectively in the quarter-finals. Atleti, three-time runners-up, edged Barcelona in a dramatic rollercoaster, winning 2-0 at home before surviving a scare in the return when Ademola Lookman steadied the tie. Arsenal, 2006 finalists, took a more controlled route, grinding out a 1-0 victory away at Sporting CP before a disciplined 0-0 at home. These four sides are all hunting either a first or another Champions League crown, and their paths to this stage underline contrasting identities: free-scoring holders and serial winners on one side, defensive resilience and tactical structure on the other.
Predicted Champions League Lineups and Key Absentees
UEFA’s Champions League lineups projections point to both semi-finals starting at near full strength. Paris are expected to line up with Safonov; Hakimi, Marquinhos, Pacho, Nuno Mendes; Zaïre-Emery, Vitinha, João Neves; Doué, Dembélé, Kvaratskhelia, with coach Luis Enrique noting that only Quentin Ndjantou is unavailable. Bayern should counter with Neuer; Stanišić, Upamecano, Tah, Davies; Kimmich, Pavlović; Olise, Musiala, Luis Díaz; Kane, with Harry Kane chasing more goals after scoring in his last five Champions League outings. In Madrid, Atleti are tipped to start Oblak; Molina, Pubill, Le Normand, Ruggeri; Simeone, Llorente, Koke, Álex Baena; Griezmann, Álvarez. They miss Barrios and Giménez, while Hancko and Lookman are doubts, potentially limiting Simeone’s rotation options. Arsenal’s predicted XI is Raya; White, Gabriel, Saliba, Hincapié; Rice, Ødegaard, Zubimendi; Saka, Gyökeres, Martinelli, with Merino, Timber and key late-goal specialist Havertz ruled out, subtly reducing Arteta’s attacking flexibility from the bench.
Champions League Records and Semi-Final Memories
Champions League records give useful context to these ties. Bayern are the seasoned campaigners: 21 previous semi-finals with 11 ties won, including a 7-0 aggregate demolition of Barcelona in 2012/13, still the biggest winning margin ever in a semi-final. Atleti have contested six semi-finals, winning three. Their standout moment came in 2013/14, when Diego Simeone’s side stunned Chelsea 3-1 at Stamford Bridge after a goalless first leg, securing a first final appearance in the competition for 40 years. Arsenal’s semi-final history is shorter: three previous appearances, winning once. Their defining tie was against Villarreal in 2005/06, when Kolo Touré’s goal at Highbury and Jens Lehmann’s last-minute penalty save in Spain carried them to their only final. Paris, meanwhile, are back in the last four as holders, aiming to reach a second consecutive final after last season’s comeback semi-final aggregate win over Arsenal.
Discipline, Atmosphere and the ‘Advantage Arsenal’ Debate
Off the pitch, Arsenal’s recent UEFA fine has attracted headlines but is unlikely to alter the competitive balance. The club were sanctioned after a firework was lit during their away match at Bayer Leverkusen, a game they drew late through Kai Havertz before winning the return leg 2-0 at home. UEFA also fined Sporting CP for object-throwing in Lisbon, where Arsenal again showed control, winning 1-0 and then holding out for a 0-0 to reach the Champions League semi finals. These incidents reinforce UEFA’s stance on supporter conduct, but the modest punishment will not affect squad availability or allocations. Atmosphere-wise, Atleti’s Metropolitano remains one of the loudest venues in Europe, though Arsenal’s composed performances in hostile arenas this season suggest they will not be easily rattled. Any ‘advantage Arsenal’ narrative rests more on their organisation and defensive record than on disciplinary subplots.
Tiny Edges: Home Legs, Styles, Squad Depth and How to Watch
The details that decide semi-finals are often small. First-leg venues matter: Paris and Atleti host initially, tasked with building a lead without overcommitting. Arsenal may quietly welcome playing the decisive second leg in North London, particularly given their miserly defence of just five goals conceded in 12 matches, while Atleti’s prolific 34-goal campaign suggests a classic ‘attack vs defence’ dynamic. Bayern’s depth and experience in two-legged ties could be decisive if their high-tempo approach forces Paris to rotate, whereas Paris’s near-clean bill of health gives Luis Enrique tactical flexibility across both matches. For supporters, both UEFA previews list global broadcast partners, and UEFA’s digital platforms will carry build-up and live coverage. Storylines to track include Marquinhos chasing a Brazilian Champions League appearance record, Harry Kane’s scoring streak, Atleti vs Arsenal as a clash of philosophies, and whether either challenger can disrupt Bayern’s and Paris’s recent Champions League records.
