Chelsea's struggles this season are well documented. The Blues sit in 14th in the Premier League after 14 games having won just four games so far. What could possibly make their campaign even worse? How about two of their former players who were deemed not good enough absolutely killing it this year.
Both Romelu Lukaku and Kevin de Bruyne were deemed surplus to requirements at Stamford Bridge, and sold for a combined fee of £48 million to Everton and Wolfsburg then Manchester City respectively.
The Belgian duo have been in incredible form this season, with Lukaku bagging 13 goals across all competitions after scoring against Middlesbrough, while De Bruyne's double in Manchester City's 4-1 Capital One Cup win against Hull last night took his total up to nine for the season.
De Bruyne also has eight assists and Lukaku has four - meaning each has been involved in 17 goals for their respective teams this season. Chelsea, meanwhile, have only managed 17 league goals all season long.
That point didn't go unnoticed on Twitter by Chelsea fans, who didn't miss the chance to stick the boot in after the damning statistics were flagged up by Sky Sports.
Both Lukaku and De Bruyne left Chelsea under a cloud after reported bust-ups with boss Jose Mourinho. Lukaku made just 10 league appearances for the west London club after arriving from Anderlecht for £18 million in 2011, and Mourinho accused the 22-year-old of 'not being motivated' to fight for a first-team spot following his 2014 switch to Everton.
Following his exit before last season, De Bruyne claimed he'd only spoken to the Special One 'twice' during his two-and-a-half year stay with Chelsea. The 24-year-old was named the Bundesliga player of the season last term for his performances with Wolfsburg, before his £55 million switch to Manchester City earlier this summer.
