Late penalty saves City
MANCHESTER CITY escaped with a 1-1 draw against Borussia Dortmund, and it had goalkeeper Joe Hart's heroics and a 90th minute penalty goal to Mario Balotelli to thank for it.
Neven Subotic's handball, and Balotelli's subsequent penalty, gave City some redemption after Christiano Ronaldo's last-minute goal for Real Madrid had consigned the EPL champions to a loss in the final minute a fortnight ago.
The Zenit St Petersburg versus AC Milan game was also a thriller, Milan bouncing back to win 3-2 after giving up a two-goal advantage.
Tomas Hubocan turned the ball into his own net in the final 15 minutes, breaking his team's 16-game unbeaten streak on home soil.
Real Madrid stayed top of Group D after demoralising Ajax 4-1, with Ronaldo scoring a hat-trick.
In other results, Porto left it late in its 1-0 victory over Paris St Germain, Schalke drew 2-2 against Montpellier, Dynamo Kyiv beat Dinamo Zagreb 2-0 and Arsenal enjoyed a comfortable 3-1 win over Olympiacos.
The Gunners recovered from a slow start, a moment of brilliance from Gervinho putting them in front after 42 minutes, to remain on top of Group B.
