Galatasaray pushed Juventus to the brink of elimination from the Champions League with a wild 5-2 comeback win in Istanbul on Tuesday.

Trailing 2-1 at halftime in the playoff match at RAMS Park, the Turkish giant powered back after the break. Noa Lang scored two of Galatasaray's four second-half goals to stun two-time European champion Juve.

Galatasaray take a three-goal lead into the second leg in Turin next week with the chance to advance to the round of 16 for the first time since 2014.

Juventus responded well to going a goal down through Gabriel Sara after 15 minutes, with Teun Koopmeiners equalizing a minute later and adding another before halftime.

But Galatasaray took control in the second half half. Lang leveled four minutes after the restart, scoring from close range.

Davinson Sánchez gave the home team the lead on the hour and Juventus' challenge was made all the more difficult when Juan Cabal was sent off 22 minutes after coming on as a halftime substitute.

Lang got his second when capitalizing on sloppy play from Juventus' defense in its own box and Sacha Boey drove in from the angle in the 86th.
