Wayne Rooney's work ethic and 'lackadaisical' approach was of concern to Birmingham City chiefs including minority owner Tom Brady.
The remarkable admission from the NFL legend has been revealed in an upcoming five-part Amazon Prime series 'Built in Birmingham: Brady and the Blues'.
In it, Brady admits to being worried about the dedication of the Manchester United legend during his disastrous spell at St Andrews. Rooney was sacked in January last year, lasting just 15 matches in the Blues' dugout.
Under his management, the Blues took 10 points from a possible 45, losing nine and winning just two.
