MANCHESTER, England - Manchester City stand on the verge of a second successive group-phase exit from the Champions League after a 2-2 draw at home to Ajax on Tuesday left their hopes hanging by a thread.
Sloppy defending saw City fall 2-0 down to a pair of early goals from Siem de Jong, and although the English champions rallied and drew level through Yaya Toure and Sergio Aguero, the last 16 remains an unlikely objective.
The result left Roberto Mancini's men with two points from four games and even victories in their remaining Group D games against Real Madrid and Borussia Dortmund may not be enough to keep them in the competition.
Mesut Ozil saved Madrid with a brilliant late free-kick to earn a point in an entertaining 2-2 draw with Borussia Dortmund in the Santiago Bernabeu.
The Germans lead Group D with eight points, one more than Madrid, with Ajax on four points and Manchester City on two.
Paris Saint-Germain moved to the cusp of qualification for the last 16 with a 4-0 defeat of Dinamo Zagreb 4-0 at the Parc des Princes.
Goals from Alex, Blaise Matuidi, Jeremy Menez and Guillaume Hoarau guided the Parisians to a third win from four matches in Group A, lifting them onto nine points, one behind leaders Porto, who were held to a goalless draw at Dynamo Kiev.
Hosts Schalke 04 came back from two goals down to earn a 2-2 draw with Arsenal to leave the Royal Blues top of Group B.
Having lost 2-0 to Schalke at home a fortnight ago, Arsenal shot into an early lead as England's Theo Walcott and France's Olivier Giroud netted to leave the Royal Blues stunned at the sold-out Veltins Arena.
But Holland striker Klaas-Jan Huntelaar pulled one back for Schalke on the stroke of half-time, then Peru forward Jefferson Farfan netted the equaliser midway through the second half to claim a point.
The draw leaves Schalke top of the table with eight points while Arsenal are just a point behind in second, with Olympiakos third on six points after their 3-1 win over bottom Montpellier, leaving all still to play for in the group.
Competition debutants Malaga held seven-time champions AC Milan to a 1-1 draw at the San Siro to secure qualification for the knockout phase.
AC Milan are on five points, but benefited from Anderlecht's 1-0 victory against Zenit St Petersburg and hold on to second place.
