Naples, Italy – Edison Cavani scored twice as Napoli defeated 1, on Tuesday in Champions League Group A play, leaving the English Premier League leaders on the brink of elimination.
Cavani scored in the 17th and 49th minutes and Mario Balotelli could only pull one goal back for Manchester City, which lost on the road for the second time in three Champions League matches.
Bayern Munich wrapped up Group A on Tuesday with a 3-1 win over Villarreal and now the English squad must beat the German side on Dec. 7 at Etihad Stadium to have any chance to overtake Napoli for second place and a knockout berth.
Bayern, Inter Milan and Benfica were the three clubs to secure knockout berths on Tuesday.
Napoli visits Villarreal for its last match Dec. 7. Villarreal has dropped all five of its matches and has been outscored 12-2.
But City's potential exit after the "Group of Death," labeled the toughest of the competition, is even more surprising than the Spanish side's struggles.
Manchester City has been in impeccable form in England, winning 11 of 12 games to establish a five-point lead over rival Manchester United - which will also need a result in its last group match to advance.
City has won all six home games in the Premier League and has five wins and a draw on the road, but the Champions League has not been as kind as Napoli took a point in their first meeting in Manchester, and City has lost at Bayern and Napoli.
After Cavani scored the opener on 17 minutes, in-form Balotelli tied the match in the 33rd, but Cavani followed with his fourth goal of the competition after the break, and Napoli maintained its second lead over the final 40 minutes at the Stadio San Paolo.
The third place side in each group drops into the Europa League, but it would mark an enormous failure for City, especially considering its EPL form.
City is one point behind Napoli in third place, but a draw would not be enough to move up to second should the Italian side lose to Villarreal, meaning a win over Bayern is the only option.
Manchester United 2, Benfica 2
Manchester, England - Pablo Aimar scored in the 59th minute as Benfica escaped Old Trafford with a 2-2 draw on Tuesday that secured its place in the final 16 of the Champions League, and left Manchester United in need of a result in its last match in Group C at Basel.
Phil Jones' own goal inside 3 minutes gifted Benfica the lead in Manchester, but Dimitar Berbatov delivered the tying goal in the 30th minute in a rare appearance and Darren Fletcher put United ahead in the 58th.
However, Aimar followed Fletcher's goal just 80 seconds later to help Benfica earn the crucial road point to seal its advancement. United is second in the group, and a draw against Basel will be enough to advance.
To win the group, though, United needs Benfica to lose or draw against Otelul - which has lost all five of its matches to date - and defeat Basel.
Jones was unlucky to hand Benfica the lead, as a cross from the right bounced off two of his teammates to set him up for disaster, and the turned the ball into the middle of the net from about 5 yards.
Berbatov leveled off a cross from Nani with a perfect header to the far post, and Fletcher tapped in his own rebound early after halftime. But before fans had stopped celebrating, Aimar added Benfica's second goal from close range.
Although second place likely presents a tougher matchup in knockout play, it's a spot that produced two finalists in 2010 when Inter Milan and Bayern Munich finished second in their groups but advanced to the final.
Bayern Munich 3, Villarreal 1
Munich, Germany - Franck Ribery scored twice, Mario Gomez added his Champions League leading sixth goal, and Bayern Munich secured first place in Group A - the "Group of Death" - with a 3-1 win over Villarreal on Tuesday.
Ribery scored the opener after 3 minutes off an assist from Toni Kroos, then a shot off the right post from Anatoliy Tymoshchuk fell into space for Gomez for an easy finish in the 24th.
Villarreal, which has lost all five of its matches, pulled one goal back early in the second half through Jonathan De Guzman, but Kroos found Ribery again in the 69th and the Frenchman completed his brace at the Allianz Arena after he rounded the goalie and slotted into an empty net.
Bayern ends the stage at Manchester City on Dec. 7, when the hosts need a win to have any chance of advancing to the knockout stage. Bayern won the previous meeting in Munich, 2-0.
Villarreal has been eliminated, but will try to end group play with a win over Napoli on Dec. 7 in Spain.
