Accrington's performance at the Proact Stadium last month was the catalyst behind Chesterfield's move for manager Paul Cook.
The Spireites have been without a manager since John Sheridan was relieved of his duties at the end of August. Tommy Wright has been in caretaker charge since but five wins, including a 4-3 victory over Cook's Accrington side on September 18, was not enough for the Scot to land the job on a permanent basis.
Stanley's football impressed many in attendance that night, most importantly Chesterfield chairman Dave Allen and chief executive Chris Turner.
"I think Accrington are the best side we've seen here this year, they played good, attractive football and were unlucky to lose on the night actually," said Allen when speaking about Cook, who has been given a two-and-a-half year deal. "That impressed me and from that day on we have been asking ourselves 'why can't we play like that?' The budget at Accrington is around half of what it is at Chesterfield, which is in the top four or five in the division.
"I thought it was only right at the time to give the opportunity to Tommy and Mark to have a go. I think you should always try to promote from within in any business but it didn't turn out to be tremendously successful."
Turner added: "When we played Accrington we decided then that if we were to look outside the club then he [Cook] was the route we would go down and this is the man we would like to talk to. The way the team played impressed everyone I think."
