20:05 CET - The drama continues in Istanbul! Galatasaray have come from behind to take a 3-2 lead after a brilliant set-piece goal! The home side had a free-kick out on the right side in a perfect position to whip in a teasing cross and that is exactly what Gabriel Sara did.
The brilliant Brazilian's whipped delivery was deftly flicked on and into the back of the net by Davinson Sanchez.
19:55 CET - WHAT A START TO THE SECOND HALF! Noa Lang has scored his first goal for Galatasaray, tapping home to make it 2-2. What a game it has been.
19:51 CET - The second half is underway, and hopefully these 45 minutes are a lot like the first!
19:35 CET - It is half time in Istanbul, and what a 45 minutes it has been. Both teams have gone for it, and the game has been played in fast-forward. However, Juve have capitalised on some errors from Galatasaray, who have been consistently caught on the counterattack, and lead 2-1.
19:18 CET - What an absolute stunner from Teun Koopmeiners! The Dutchman has pinged in an incredible strike for his second of the game to give Juventus the lead, and Galatasaray have work to do now.
19:02 CET - Would you believe it... Juventus have equalised just a minute later, with Teun Koopmeiners tapping into an empty net. What a start!
19:01 CET - Galatasaray have taken the lead, and it is Gabriel Sara who has capitalised on some sloppy Juventus defending to slot home brilliantly! Advantage to the Turkish side.
18:57 CET - It has been a good start for both teams, with the contest being played at some intensity so far. However, no real clear-cut chances yet.
18:45 CET - Right then, we are underway in Istanbul! This could be a cracker!
17:40 CET - The lineups are in for today's early match between Galatasaray and Juventus in Istanbul, which kicks off at 18:45 CET.
With Jonathan David, Dusan Vlahovic and Arkadiusz Milik all injured, Luciano Spalletti has set Juve up with no recognised striker today, but plenty of skill with Kenan Yildiz and Francisco Conceicao on the flanks.
For Gala, Victor Osimhen starts up top with Noa Lang off the left, but Mario Lemina is suspended, which is a blow to the hosts. Star winger Leroy Sane starts on the bench, as he's not fully fit.
