You would still take calls from your manager though, even if only to ask him to speak instead to your agent - basic courtesy
I have no issue with him taking the opportunity for full time and an increase in salary along with Warburton, Montrose, Lloyd, Walker etc but the manner of his leaving says yes he has burnt his bridges in my book - good luck at Chorley
I admit to being overly precious when it comes to perceived slights to my beloved club, in fact it is unforgivable for me
