Tottenham have lost a senior figure to Manchester United just days before the end of the transfer window, according to a report.

The unofficial Tottenham academy Twitter account claimed on Sunday that Kieran McKenna has quit his post as Spurs Under-18s manager to join United.

It is said that McKenna will be involved in the Under-23s set-up at Old Trafford and that he isn’t taking the vacant Under-18s coach job.

The Tottenham academy Twitter account has developed a reputation for breaking stories, revealing last month that Spurs wonderkid Marcus Edwards had signed a new contract with the club.

United have restructured their youth set-up this year and pursued Tottenham academy director John McDermott to spearhead the Old Trafford system before appointed Nicky Butt to the role.

Butt has been given overall responsibility for reviving the club’s struggling youth system amid fears it has slipped behind rivals Manchester City as well as the likes of Tottenham and Chelsea.

Butt, a member of United’s famed Class of ’92, has taken the job that Brian McClair vacated last year and is overseeing a revamp that was kickstarted in February with the departure of youth coach Paul McGuinness and followed with the exit of youth player recruitment chief Derek Langley.

Butt’s task is to try to restore United’s reputation for nurturing outstanding talent and aim to bridge the gap between the academy and the first team to ensure a  steady flow of youngsters into the senior ranks.

In other Tottenham news, Spurs have offered a £70,000-a-week deal to land a £20million signing by Wednesday.
