It's only human to think about what could have been.
For football fans, this usually involves that young talent that got away, the transfer that came so close to completion or the star that turned their back when the club needed them most.
To celebrate the launch of Football Manager 2014, the team that developed the game has painstakingly simulated what the Premier League would look like if pivotal transfers and sackings did or didn't happen.
What if Robin van Persie, Cesc Fabregas and others had stayed at Arsenal? What if Steven Gerrard joined Chelsea and what if Jose Mourinho never left Stamford Bridge?
Now - finally - we have the answers.
Football Manager 2014 is available for Windows PC, Mac and Linux now.
