The German defender denied City a draw in Munich at the death, courtesy of a shot which deflected off team-mate Mario Gotze and past Joe Hart.
Chelsea were unable to transfer their imperious Premier League form to the European arena, letting an early lead slip to draw 1-1 with Schalke at Stamford Bridge.
Cesc Fabregas put Chelsea ahead, sliding home after a one-two with Eden Hazard on just 11 minutes.
Jose Mourinho’s men were unable to close out the contest however, with Klaas Jan Huntelaar stealing a point for the visitors. The Schalke striker pinched the ball from Fabregas before firing home, thwarting Chelsea’s hopes of a fast start to this year’s tournament.
Former Arsenal striker Gervinho bagged a brace as Roma beat CSKA Moscow 5-1.
Mediocre players from overseas are taking places in club squads that should be going to young English players, claims Football Association chairman Greg Dyke.
The FA has announced proposals to cut the number of players from outside the European Union coming into the English game by up to 50 per cent, including banning clubs sending such players out on loan, preventing Football League clubs from signing them and making the appeals process much tougher.
Some 122 overseas players were granted visas between 2009 and 2013, 23 of them in the Football League.
Dyke said: “Everyone recognises the present system is bust. The rules say elite non-European players – the very best – should be allowed to come in and we agree with that.
“What we are saying is there are a lot that aren’t the very best, that don’t play that much and do take squad places and a lot particularly in the Football League disappear after a year or so. The system doesn’t work at the moment.
“What we are saying is ‘let the best players come in but give the rest of those squad places to young English kids’.
“We still have the problem of good kids aged 17 and 18 not getting enough competitive football so we are still looking at how we improve that position.”
England finished their Women’s World Cup qualifying campaign with a 100 per cent record as forward Eni Aluko’s hat-trick helped secure an emphatic 10-0 win against Montenegro.
