The Champions League semi-finals represent the "business end" of Europe's premier club competition, a stage where "heroes are made and Ballon d'Or winners forged," as BBC Sport Senior Journalist Alex Bysouth aptly puts it. With Paris St-Germain facing Bayern Munich and Atletico Madrid clashing with Arsenal, the path to the final in Budapest hinges on individual brilliance and tactical masterstrokes.

This stage isn't just about the biggest names, but about those players whose unique contributions could prove vital. Opta has positioned Arsenal as marginal favourites to lift the trophy this season, ahead of Bayern Munich, highlighting the fine margins at play.

Midfield maestros and defensive anchors

In the heart of the midfield, Bayern Munich's Joshua Kimmich stands out. He has made 19 defensive line-breaking passes, the most in the Champions League, and has delivered the ball into the penalty box more than any other player this season. Kimmich's ability to unlock defences will be crucial against a formidable PSG side.

For Paris St-Germain, Vitinha is the engine room. The Portugal international has completed 1,370 passes this term, the most in any edition of the Champions League since Opta began tracking statistics in 2003-04. His influence is profound, with Alex Bysouth noting that "his passing stats put Vitinha in the conversation with Barcelona and Spain great Xavi." Vitinha has completed 100 or more passes in eight different games this season, a feat only topped by Xavi in the 2010-11 campaign.

Atletico Madrid's defensive solidity often starts with Matteo Ruggeri, who has featured in 11 of their 14 Champions League games this season. With Atletico employing a low block 458 times this campaign, Ruggeri's defensive prowess is key. He ranks third overall in the competition with 20 interceptions, and no Atletico player has won more tackles. BBC Sport suggests Ruggeri's next challenge could be to "stifle Arsenal's Bukayo Saka," a testament to his defensive assignment capabilities.

Arsenal's own defensive foundation is built upon the consistent trio of David Raya, William Saliba, and Gabriel Magalhaes. In 22 Champions League games started together:

They have kept 13 clean sheets.
They have conceded just 11 goals, averaging a goal conceded once every two games.
They boast a record of 59% of matches without conceding.

Raya, in particular, has been exceptional, saving 90% of shots faced in this season's competition.

Attacking catalysts and prolific finishers

The return of Bukayo Saka could be transformative for Arsenal. Having missed over a month with an Achilles problem, his presence significantly boosts the Gunners' attack. Opta statistics reveal:

With Saka: Arsenal average 2.6 goals and 2.3 expected goals (xG) per game in 8 matches.
Without Saka: Arsenal average 1.5 goals and 1.8 xG per game in 4 matches.

For Paris St-Germain, the attacking thrust from the flanks is potent. Achraf Hakimi and Nuno Mendes are long clear among defenders for involvement in attacking moves per game, averaging 7.5 and 7.6 respectively. Hakimi has contributed five assists and one goal in the competition, with legendary Brazilian right-back Cafu claiming he is "the best in the world in that position." Khvicha Kvaratskhelia, also of Paris St-Germain, has been directly involved in 13 goals this season, scoring eight and assisting five.

Bayern Munich's attack features the electrifying Michael Olise, who has completed the third-most dribbles and created the third-most big chances in the competition. Overall, Olise has accumulated 20 goals and 29 assists in all competitions, making him a constant threat.

Atletico Madrid's offensive hopes largely rest on Julian Alvarez, who has scored nine goals in the Champions League this season – a record for an Atletico player in a single campaign. His relentless work rate is also evident, with 853 high-intensity pressures this season, averaging 70 per game.

Finally, Harry Kane leads the line for Bayern Munich. "Goals win games, and the England captain has scored 53 of them in 45 games in all competitions for Bayern Munich this season," states Alex Bysouth. Kane has scored in his past four Champions League knockout games, and his 12 goals are the most by an English player in a single Champions League season. A first European trophy and potentially a Ballon d'Or could hinge on his continued prolific form.
