Manchester United – 2002/03
Trailing by eight points is bad news already, but doing so twice is normally considered a complete disaster.
For Sir Alex Ferguson, however, nothing is impossible.
After a 3-1 Boxing Day defeat to Middlesbrough, Manchester United won 15 of their final 18 games without a single loss to snatch the Premier League crown from holders Arsenal by five points.
It was an incredible comeback, and a fitting way for David Beckham to end his Old Trafford career.
