Roberto Mancini made a dramatic start as Galatasaray coach on Wednesday when his team took a shock lead and then fell behind before scoring a late equaliser in a 2-2 draw at Juventus in the Champions League.
Didier Drogba pounced on a defensive blunder in the first half to open the scoring for Galatasaray.
The visitors held on until Arturo Vidal levelled with a controversial penalty in the 78th minute and Juve then went 2-1 up with a Fabio Quagliarella header in the 87th.
The Italian team barely had time to celebrate before Umut Bulut took advantage of more slack defending to score, leaving Juve with two points from two games in Group B and Galatasaray with one.
Real Madrid lead the way with six points after their 4-0 win over Copenhagen (one) on Wednesday.
Juve started slowly and gifted the Turkish side the lead after 36 minutes.
Leonardo Bonucci made a hash of a back pass which Drogba intercepted. Keeper Gianluigi Buffon then rushed prematurely out of his area, allowing the Ivorian to slip the ball through his legs and into the net.
The hosts struggled to create openings but equalised out of the blue with a penalty when Quagliarella's legs crumpled under the softest of challenges and Vidal fired the ball into the roof of the net.
Mancini was left shaking his head on the touchline and there was worse to come when Quagliarella headed in with three minutes left.
It was then Juve coach Antonio Conte's turn to suffer when Bulut levelled.
