It was a rollercoaster season for Fabien Causeur who, as always, was ready to deliver when the lights shined brightest. In his 12th Turkish Airlines EuroLeague season and sixth with Real Madrid, Causeur passed the 300-game mark in the competition, becoming the first French player to do so. He took part in 25 regular season games and averaged 4.0 points and 1.3 assists in 13 minutes per night. Causeur was strongest when seeing extended playing time, reaching double digits in scoring three times. He scored 11 points in victories against ALBA Berlin and Maccabi Playtika Tel Aviv and a season-high 14 in a 71-75 road win at LDLC ASVEL Villeurbanne, in which he missed one only shot and reached a PIR of 23.
Causeur did not play in the last three games of the playoffs as Real rallied to beat Partizan Mozzart Bet Belgrade in five games. He was also held scoreless in the semifinal against FC Barcelona. Before the championship game, Causeur faced some off-court problems: his pregnant wife Lucy was very sick and spent the previous night at the hospital, but recovered in time to be in the stands to see her husband play against Olympiacos Piraeus. Causeur has a reputation for bringing out his best at the Final Four, including a memorable 2018 championship game against Fenerbahce Beko Istanbul. Against Olympiacos, Causeur did it again.
