Galatasaray have a shock lead at Juventus after 45 minutes of Roberto Mancini's first game in charge, with Didier Drogba putting the visitors ahead in Turin just before the break.
Juve boss Antonio Conte picked an attacking lineup featuring Carlos Tevez and Mirko Vucinic but were restricted to keeping the ball deep early on, with Gala happy to sit and wait for chances to counter.
Paul Pogba failed to connect with an acrobatic volley in the box as Juve began to build momentum, while at the other end Drogba forced Gianluigi Buffon into a smart save at his near post.
The Old Lady suffered a setback midway through the first half as Vucinic was forced off after appearing to pull his hamstring, with Fabio Quagliarella introduced in his place.
Gala grew in confidence as the first half progressed and took the lead 10 minutes before the interval, with Drogba applying the finishing touch.
The veteran seized on a sloppy backpass by Leonardo Bonucci, controlling before tucking into an empty net to put Mancini's side in front.
