Manchester United owner Malcolm Glazer has died aged 86, his NFL franchise the Tampa Bay Buccaneers have announced.

Glazer controversially became owner of United in May 2005 and his tenure was an uneasy one, with many fans unhappy at the level of debt his takeover had put on the club, who have largely continued to prosper ever since.

It is understood Glazer's death will not have any significant effect on the ownership of the Premier League club, with the family retaining a 90 per cent share. 

A spokesperson for the Old Trafford outfit said: "The thoughts of everyone at United are with the family tonight."
