3. Manchester United, 2011/2012

It's not often you see a massive points swing in the season - here we saw two.

Manchester City raced into pole position in the Premier League and by the start of 2012 were clear favourites for the league.

They'd humiliated rivals Manchester United, and were looking a shoe-in for the title.

However, a series of poor results coupled with United's resurgence left things in the balance.

When the Citizens lost 1-0 away to Arsenal it left the Red Devils eight points clear with just eight games remaining.

Roberto Mancini all but conceded the title.

And it took up until the very last second of the season - in fact a few minutes after most teams' seasons had ended - for the winner to be decided.

Sergio Aguero's historic last-second strike sent the trophy to City and wrapped up an incredible fight back for the title.
