Southgate said: “Twenty minutes into the second half after they had scored twice like that, I would have settled for a replay then.
“We were very good in the first period and could have had more. But all the good things we did in that first half we stopped doing after the break and City took advantage.
“City had spirit and passion. We have been on a good run of late but what happened here shows we are not quite there yet, you cannot afford to take your foot off the gas.”
