Regan leaves with the best wishes of everyone at the Dennyfield having recently been successful in gaining a position at a Premiership club and as a result he cannot give the commitment that is required to continue his work at Thackley.
Regan said: “I have been given a great opportunity to coach at one of the biggest clubs in the world - certainly the biggest in my eyes - on a part-time basis. It is therefore with deep regret that I have to resign from my post at Thackley due to my new commitments, and I wish the club all the best in the coming years, because they are definitely a progressive club.
“Initially, a number of years ago I came to Thackley to gain some coaching experience when I was taking my UEFA `A` licence. Following a season as manager at Liversedge and a spell in a coaching position with Scunthorpe United, I little realised that four years later and after working with four different managers I would have been back at Thackley.
“It has been a fantastic experience that I will never forget. It seems like I have been around the block working at grassroots non-league, and at professional clubs but it is all good experience, and I see this as another new venture.
“I wish to say a big thank you to everyone involved at the club who have supported me throughout my time there - the committee, the volunteers who help to keep the place running and especially the players. I will definitely miss the lads around the club and the banter, but I think they will understand how it is.
“Who knows - one day I may be back in the non-League game, because it does have a special effect on you once you get the bug.”
