Steven Gerrard came agonisingly close to signing for Chelsea in the summer of 2006.
He opted to stay at Liverpool and will probably go down as one of the greatest players never to win the Premier League.
It could have been so different if he had joined the revolution at Stamford Bridge as the simulation predicts that he would have won five Premier League titles with Chelsea.
Not only this but he would have also won two FA Cups and two Champions Leagues.
In other words, he would have turned Chelsea in to the dominant force in Europe.
