Manchester City 1-1 Chelsea: Lampard haunts his former club and 4 other things we saw at the Etihad

Jose Mourinho likes to keep things tight when his Chelsea side visit their rivals - and so it was again today for most of the game. Last season, the Blues performed a smash-and-grab to win by a single goal at the Etihad and they appeared to have repeated the trick today, only to see a former hero cancel out their lead in the 85th minute. After relative disappointment for both teams in the Champions League this week, it was the hosts who started brighter - no doubt feeling they had a point to prove after being out-classed and out-passed for large parts of the evening against Munich on Wednesday. But if that game was primarily a test of their defensive credentials, today's instead presented Manuel Pellegrini's men with an entirely different tactical challenge - that of breaking down a stubborn and well-drilled side while protecting themselves from being hit on the counter attack. They were the more dangerous of the two sides until Pablo Zabaleta saw red, but Chelsea made their man advantage count after Andre Schurrle gave them the lead. Jose Mourinho will be left cursing a moment of lax defending as ten-man City were able to regroup following the goal and it fell to none other than Frank Lampard to do the business against his old club. What did we learn from today's 1-1 draw at the Etihad?
