Dmitri Halajko joined Norwich City's academy in the summer of
2012. He had previously been the Football Association's head of
coaching development in the Eastern region.
Prior to this, he had worked for Colchester United's centre of
excellence for 11 years.
After a year working with the FA, he returned to Norwich to assist
Under-18s manager Jerry Gill as Professional
Development Coach. In December 2014, a restructuring within the
academy saw him appointed as Lead Phase Coach for the Professional
Development Phase with the team coaches Graeme
Murty (Under-16s), Jerry Gill
(Under-18s) and Paul Wilkinson (Under-21s)
working under him. His role is to make sure now that rather than
having three teams there is one group of players, considering
them as a group rather than three different strands.
In August 2015, he was appointed to the role of managing Norwich's
Under-21s, assisted by Darren Huckerby.
It was announced at the beginning of February 2015 that Halajko would be leaving Norwich for a senior operations role with a Premier League side. This was later revealed to be Leicester City.
On 2nd July 2019, it was reported that Halajko had joined West Ham as their Lead Academy Under-23 coach having been recruited by former City colleague Ricky Martin. Martin told West Ham's website: "I am really pleased that Dmitri has agreed to join us and it is a real coup to have appointed someone of his experience and ability.I have seen at first hand his quality and talent as a coach, both in sessions on the training pitch and working with players individually on their development programmes. He has fantastic experience at academy level and a proven record of progressing elite players through to first team level. His style and approach will fit in perfectly to the West Ham way that we encourage and nurture here at Chadwell Heath."
Dmitri left West Ham in November 2021 to take up a youth and coaching development role at the Premier League. He was replaced by Mark Robson
