Manchester United chief executive David Gill was involved in a tense exchange with a fan on Thursday over the club's owners, the Glazer family.
The Daily Mail says Gill got involved in a terse exchange with a fan during a visit to Birmingham University on Thursday as the simmering anger over the Glazer ownership at Old Trafford rumbled on.
The row began when Gill was approached after a question-and-answer session about football finances and was asked to explain comments he put his name to when United were attempting to turn the Glazers' takeover bids down in 2004.
Although Gill attempted to put across his stance, his assessment of the situation was repeatedly questioned.
In defending United's controversial owners, Gill countered: "How many leagues have we won in the last three years?"
He also questioned: "Why are they leeches?" when that claim was made about the American family.
