Owen Hargreaves has revealed how he took Sir Alex Ferguson to task for severe criticism of his inability to push through the pain barrier when suffering from tendonitis in his knee.
The former Manchester United manager described England midfielder Hargreaves as 'one of the most disappointing signings of my career' and his time at Old Trafford a 'disaster' in his 2013 autobiography.
Hargreaves won the Premier League and the Champions League in his first season at United in 2007-08 but appeared only sporadically thereafter as he fought to save his career amid the intense pain of his knee problems.
