I just know the story that's been told on all the newspapers.
Grew up, English grandmother, didn't like how Robson was running Porto and it just so happened that he lived in the same apartment as him, would wait on the stairwell for him to come. He would sketch out tactics and explanations for Robson and put it in his mailbox, Robson helped him learn at Ipswich and Scotland. Mourinho became coach at Porto and he asked AVB to come along, rest is history.
Might have to wait for the autobiography. Speaking of football books, that Sid Lowe Barcelona-RM book sounds to be a banger.
The Bergkamp book that came out this week as well.
