"My initial reaction was one of shock, I couldn't believe it. It's just a tragedy, it's terrible. This has left a lot of people devastated including myself and it puts football into perspective when you get news like this coming in. It's difficult to take and difficult to accept and as with a lot of people, my thoughts turn to his family, its just shocking news."
"I go back a long way with Keith and he signed me three or four times, it was Keith that brought me to Bury. It's shocking and my thoughts are with the family who I can only imagine are devastated, as will a lot of people be."
"To a lot of the lads I know, he wasn't just the gaffer when we played under him, he was a good friend as well. He always had time for you as a person and was just a great guy, he was genuinely a great guy and I think you will struggle to find anyone who has a bad word to say about him."
"It was a massive shock, I spoke to Richard Butcher who travelled back to Lincoln with him on Tuesday night and he said that he was fine. He was in good form during the game at Notts County and when he got the phone call he was like I was, he couldn't believe it. Something like this just shows what can happen."
"Macclesfield's game at Hereford will take place and I do know one or two of the lads that will be there. Like myself they have been with Keith for a long time and we are all quite close to him. The game will be difficult for them but Keith would have wanted them to carry on. He was a football man through and through. I know the lads will do their best for him on Saturday. It's a difficult time and football takes a back seat for something like this."
"Keith Alexander was the only manager in football that could pull you in the office, tell you that you're not playing and then you come out of the office with a smile on your face. That's just the type of guy that he was. He was a real character and he will be very sorely missed."
"I know his wife and sons and my thoughts go to them, it is going to be very difficult for them."
