Huddersfield Town have appointed Mark Robins as their new manager in succession to the sacked Simon Grayson.
Robins, 43, transformed the fortunes of Coventry City this season, lifting them from the lower reaches of League One to just outside the play-off places.
His departure after just five months has angered the Sky Blues but they were powerless to prevent him from talking to Huddersfield after the Championship club met the compensation figure within his contract.
He joins a Huddersfield team which sits 18th in the Championship, three points above the relegation zone in their first season back in the second tier. Grayson was sacked last month as the club slipped towards the bottom three.
Huddersfield chairman Dean Hoyle told the club's official website: "We've been through a lengthy and detailed process in appointing Mark as the club's new manager and we are delighted.
"As I said we would, we have taken our time in making this appointment because it is such an important one, both for our short and long term ambitions. Obviously retaining our Championship status is vital, but we also needed a manager who buys into the club's football philosophy and structure. We believe Mark is that man.
"Mark has the knowledge, skills and attributes that the board of directors set out for our new manager and it is clear that he shares our vision, philosophy and values. He has good knowledge of the division from his previous spell with Barnsley.
"He has also shown an ability to develop young players. Indeed, his work with the FA on the Elite Player Performance Plan and his commitment to development was a big factor in his appointment.
"Mark has shown his skill in getting the most from the resources at his disposal, none more so than his recent achievements at Coventry; within five months he has pulled that side away from the League 1 relegation zone and given them a genuine chance of being involved in the promotion mix.
"Crucially for me, during our discussions Mark has shown a real work ethic and drive to succeed. Those qualities are a prerequisite to have any chance of success."
Coventry City chief executive Tim Fisher spoke of his "frustration and disappointment" at Robins' decision to walk out on them for Huddersfield.
In a statement published on their official website, Fisher said: "To say we are disappointed is an understatement. We gave Mark a three-year contract which we saw as a long-term appointment.
"Added to this, Mark was able to bring in those members of staff that he requested, plus we gave a considerable financial commitment in terms of players brought in during the loan windows to ensure that we had a strong, competitive team on the pitch.
"Over the last few months, we have had several clubs interested in securing Mark's services and we have fought off multiple approaches. We made every effort to ensure he stayed with us. Once it became obvious that there was no way forward we had no choice but to eventually allow him to speak to Huddersfield.
"The club went through a very rigorous process in appointing Mark, we believed in him, his management team and felt he was ideally suited to the challenge that we face at Coventry City.
"The turnaround in fortunes at the club has vindicated both the faith and trust we showed in Mark and I believe everyone - supporters and players alike - agreed that we are at the start of something very special and exciting.
"So for this departure to happen at the business end of the season and in this manner, is frustrating and disappointing in equal measure for all concerned. It is fair to say that we are all deflated by Mark's decision to go and, equally, I am sure the supporters will feel the same frustration.
"I understand that our supporters will be angry and disappointed because they have seen a dramatic turnaround in on-pitch fortunes and performances in the short space of time that Mark has been here."
