Tuesday night was largely a successful one for Antonio Conte and Chelsea. They put four past Southampton at Stamford Bridge, moved seven points clear at the top of the Premier League table, and put the pressure on second place Tottenham ahead of their trip to Crystal Palace on Wednesday night.
The one downside, however, was that they set an unwanted defensive record of 11 consecutive games without keeping a clean sheet.
Chelsea: Have gone 11 Premier League games without keeping a single clean sheet for the first time since December 1996 (13 games) #CHESOU— WhoScored.com (@WhoScored) April 25, 2017
Chelsea have certainly been less imperious in recent weeks, having looked almost unstoppable when Conte first switched to his 3-4-3 system. Defeats against Palace and Manchester United have given Spurs a glimmer of hope, and their defensive concerns have grown more prevalent.
Fortunately for Conte and his players, they are excellent going forward, and have generally been able to outscore their opposition.
A 2-0 home win against Hull City in January was Chelsea's last league game without conceding, and though a Premier League title still seems the likely outcome, Conte may be looking to address the problem ahead of a season that will include Champions League football.
The 13-game run without a clean sheet is Chelsea's longest since 1996, and is a testament to the attacking efforts of the likes of Eden Hazard in the second half of the season.
The Blues have currently scored the most goals in the Premier League, one more than Spurs with 69, and have the third most impressive defensive record, behind Mauricio Pochettino's side and Jose Mourinho's Manchester United.
