I also want NP to leave but your reasoning here is seriously flawed. The Kane for Wood change over recent games has been effective and, in isolation, was a perfectly sensible decision. He wasn't responsible for Knockaert acting like a prize cock taking the penalty opportunity away from a more reliable choice. However, this doesn't mean that Knockaert is not capable of being a very good player for us in the future. He's extremely immature, with an irritating tendency to give the ball away, but he has genuine talent.
Where I do agree is the fact that NP has had three chances now to get us promoted from this league and he's failed three times (two full seasons and one two thirds of a season). In modern history, I can't recall a City manager ever getting a fourth shot at winning promotion from this league, even without the comparative riches and budget afforded to NP.
