Brighton chief executive Barber added: “We are sorry to learn of Dan’s decision. He’s been an important part of the club’s senior management team since joining us from The FA, and he has made a significant contribution to our club’s progress in the Premier League and Women’s Super League.
“On a personal level, I will be sad to see Dan leave as we’d developed a close day to day working relationship. Dan’s been an excellent colleague and has become a good friend as well. I wish Dan and his family well for the future.
“However, as is the case with all top-quality people in any industry, we are always aware of the risk of losing key staff to a rival. With that in mind, we always put in place contingencies and succession plans that are designed to minimize the impact on our club.
“As such, our assistant technical director, David Weir, will now step up and assume the role of acting technical director. He is someone with an excellent knowledge of the role and of our club’s culture from working side-by-side with Dan.
“As previously, we will conduct a search process for the role of technical director, as it is only right to do so. We anticipate a lot of high-caliber applicants but we also fully expect and hope David will be a candidate in this process.”
Chairman Tony Bloom added, “We are extremely disappointed that Dan will no longer be our technical director. He leaves a significant legacy in place and for that we are greatly appreciative.
“Dan’s done an outstanding job and helped build on the progress the club had already made across all of our technical areas. I wish Dan and his family well for the future.”
