Did he leave or was he sacked ? either way it was time for him to move on . As much as i respect Roy keane , he did no good for ispwich , he was full of talk before joining them as manager saying he would get them into the premier league within a season, but got nowhere near it .Now , maybe that was because he was dealing with a pack of useless players ,because he did do very well with Sunderland , getting them promoted into the Premier league within a season in his first ever managing post ( fairly impressive in my book ), but still i think Ipswich board were patient enough with him and they need a manager now to come in with more realistic expectations and goals to lead them on .
Is keane cut out for management ? well he did very well with Sunderland , so i would not write him off as a failure yet, hes learning his trade as manager and keane being the man he is , im sure wont let this stuff at Ipswich distract him in anyway .
I'll bet Keane will be managing another club within a few weeks, he can only improve and learn as a manager , hes still relatively new to the job in comparison to other managers....If he can become as good at management as he was a player , then that will be one hell of a manager .As i say , he can only improve . Don't write him off yet .
