Speaking ahead of the recent matches between Arsenal and Leicester City and Chelsea and Newcastle, ex Premier League star Chris Sutton was outspoken in his view of Arsene Wenger and Jose Mourinho, in comments appearing on BBC Sport.
The 42-year-old has, like many football fans, seen the rivalry between the two managers escalate since the Portuguese returned to Stamford Bridge in 2013, but Sutton is critical of how the Gunners boss handled the recent 2-0 Chelsea win between the two sides.
"Arsene Wenger is jealous of Jose Mourinho – why wouldn’t he be? Look what Mourinho has won," Sutton is quoted as saying by BBC Sport.
"Arsene needs to take more responsibility for the actions of his players. Diego Costa's retrospective ban was right but how has Gabriel's red card been rescinded? I don’t know.
"Arsenal don’t have leadership on the pitch."
The fallout from the Diego Costa-Gabriel incident seemed to infuriate both managers at different times, and certainly Blues and Arsenal fans will have their own interpretations on how it should have been handled, but comments that Wenger will be jealous of Mourinho's success over the last few years won't go down well at the Emirates.
If either of the last couple of seasons were anything to go by, with the Blues winning the title in May, then Sutton's assertions would be a little more understandable, even if it's easy to place him firmly in the Chelsea camp with his connections to the West London outfit, and despite struggling in his one season there.
Looking at the current Premier League campaign though, it seems like Mourinho is struggling to follow up last season's title winning exploits.
The Blues are already eight points behind league leaders Manchester United, having won just two of their opening Premier League games. Chelsea lost just once in 2014/15 after New Year's Day, accumulating three defeats throughout the whole season, and already they have that number in the defence of their title.
Arsenal on the other hand, responded to their loss against the Blues last week to inflict an impressive first loss of the season on high-flyers Leicester City, and are now in a familiar position in the top four as they look to mount their own title challenge this season.
If Wenger does manage to secure the piece of silverware that has eluded him since the 2003/04 season, it may be time for the Frenchman's naysayers to move on.
