The year was 2012. A weird season for Chelsea. After winning the Champions League for the first time the previous season, league success was moderate with a respectable third place finish but not what supporters were expecting. Then they suffered Champions League elimination in the group stage, something that hadn't occurred any any of the previous nine campaigns.
During that group stage they were obliterated by Italian giants Juventus away from home. The manager of that side? Antonio Conte.
During Conte's time at Juventus he was known for deploying a 3-5-2 on many occasions and this night was one of those. Chelsea had drawn Juve, 2-2, in the reverse fixture at Stamford Bridge. However, when the two sides met up in Turin, the Italians were too much for the Blues to handle and were demolished, 3-0, on the night.
Here is a great look at the tactics used by Conte on that night and small sampling of what made his tenure at Juventus so successful. Perhaps one day we'll see his famous 3-5-2 take hold in London.
