I didn't understand taking off Nasri in the 60th minute. Seemed like a substitution with an eye on the Champions league. Thought we should have kept him on until at least the 75th, just to keep the game under control. He was dictating the game. Second, I thought it would have been a like for like with Navas for Milner. Once we lost the central midfield creativity and hold-up play that Nasri supplied we looked a different side. Another tough lesson for Pellegrini & Co., but all is not lost just yet. Puts a lot of pressure on the big games vs. the north Londoners, but at least we are usually up for defending leads the big games.
