Galatasaray begin their UEFA Champions League campaign Wednesday against Sporting at José Alvalade Stadium in Lisbon, with the Turkish champions looking to build on last season's run while trying to overcome a difficult recent record away from home in Europe.
Galatasaray earned direct entry after winning the 2025-26 Süper Lig title, their fourth consecutive championship.
They are appearing in the competition for the 19th time and will play in the 36-team league phase for the second straight season.
Sporting are also unbeaten this season and have home advantage, along with a strong record against Turkish opposition.
Another step forward
Galatasaray reached the Champions League round of 16 last season after collecting 10 points from eight league-phase matches against Eintracht Frankfurt, Liverpool, Bodø/Glimt, Ajax, Union Saint-Gilloise, Monaco, Atletico Madrid and Manchester City.
They then eliminated Juventus in the knockout playoff before losing to Liverpool in the round of 16.
Coach Okan Buruk's team will hope to go further this season, but their European away record offers cause for concern. Galatasaray have won only one of their last 15 European away matches, a 3-0 victory over Ajax last season. They have drawn three and lost 11 during that stretch.
Their record against Portuguese clubs is also unfavorable. Galatasaray have faced Benfica, Porto and Braga nine times in UEFA competition, winning three, drawing one and losing five. They are winless in their last five meetings with Portuguese opposition, losing four.
Sporting have won five of their last six matches against Turkish clubs, including their last three.
Unbeaten start, but defensive concerns
Galatasaray have collected 10 points from their first four Süper Lig matches this season. They drew with Arca Çorum FK before beating Erzurumspor FK, Göztepe and Başakşehir, including a 3-2 victory away to Başakşehir in their latest match.
The results have put Galatasaray at the top of the league, but their defense has been vulnerable. They have conceded twice in three of their four matches, with set pieces a particular concern.
That could be costly against a Sporting side that has scored 14 goals in five league matches.
Osimhen among Galatasaray absentees
Galatasaray will be without several key players. Victor Osimhen is expected to miss the match with an adductor injury, while Mario Lemina and Wilfried Singo are also sidelined. Goalkeeper Günay Güvenç is expected to miss out because of a muscle problem.
Osimhen's absence is especially significant. The Nigeria international has scored six goals in four league appearances, accounting for half of Galatasaray's 12 goals.
Gabriel Sara and Lucas Torreira will be among those expected to provide more attacking production.
New signing El Chadaille Bitshiabu could make his Galatasaray debut after joining from RB Leipzig on loan. The 21-year-old defender began training with the team Sept. 5 and could provide an option in central defense with Lemina unavailable.
Leao faces his former club
Rafael Leao could make his return to Sporting, where he began his professional career.
The Portuguese forward joined Sporting's academy in 2012 and reached the first team during the 2017-18 season, making five appearances and scoring twice. He moved to Lille in 2018 before later establishing himself at AC Milan.
Leão's younger brother, Paulo Simao, remains with Sporting's under-23 team.
Sporting enter in strong form
Sporting opened their Primeira Liga campaign with a 2-2 draw against Estrela Amadora but have since won four straight matches.
They beat Rio Ave 4-0 before defeating Nacional 2-0 at home, recording consecutive clean sheets. Sporting have scored at least twice in four of their five league matches and sit second with 13 points.
Luis Suarez leads their scoring with four league goals, while Flavio Gonçalves has three and Fotis Ioannidis has two.
Coach Rui Borges also has several promising young players at his disposal, including Gonçalo Inácio, Zeno Debast, Eduardo Quaresma, Maxi Araujo, Sergi Altimira and Rodrigo Zalazar.
Sporting reached the Champions League quarterfinals last season. They won five of eight league-phase matches to finish seventh, advanced directly to the round of 16 and eliminated Bodo/Glimt before losing to Arsenal in the quarterfinals.
First European meeting
Galatasaray and Sporting have never previously met in UEFA competition.
Sporting have faced Kocaelispor, Gençlerbirliği, Beşiktaş and Başakşehir 10 times, winning five, drawing three and losing two.
Sporting will become Galatasaray's 114th different European opponent and their 341st European match. Galatasaray have won 121 of their previous 340 continental games, drawn 90 and lost 129, scoring 468 goals and conceding 518.
Galatasaray have also played 134 Champions League matches, winning 34, drawing 32 and losing 68.
Difficult Champions League starts
Galatasaray have won only one of their last 10 Champions League opening matches, drawing four and losing five. Their lone victory came in 2018-19, when they beat Lokomotiv Moscow 3-0.
They have also won only seven of their last 30 Champions League group or league-phase matches, alongside six draws and 17 defeats.
Despite those struggles, Galatasaray remain Türkiye's most successful club in European competition. They won the UEFA Cup in 2000 by beating Arsenal in the final and followed it with the UEFA Süper Cup victory over Real Madrid.
They have also reached the European Cup semifinals once and the Champions League quarterfinals three times.
Galatasaray have scored in each of their last 39 European matches, with their last scoreless game coming in a 0-0 draw against Barcelona in the 2021-22 Europa League.
Buruk has overseen 38 European matches as Galatasaray coach, recording 15 wins, nine draws and 14 defeats.
