1-0 up with an hour played against Swansea this afternoon, Chelsea were looking good to continue an impressive start to the Premier League season. Two minutes later, they were facing a 2-1 deficit.
First, Gylfi Sigurdsson equalised for Swansea from the penalty spot after Thibaut Courtois had fouled the Iceland midfielder. Then, just moments later, Leroy Fur put the Swans ahead after he robbed Gary Cahill of the ball 30 yards out and raced through on goal unopposed.
As you might expect, Chelsea fans were in uproar. However, rather than aiming their criticism at the English centre-back, they were left furious with referee Andre Marriner after letting Fur away with what they argue is a clear cut foul. Check out the video below to judge for yourself...
Having just lost their lead, Chelsea were looking to regain their composure and keep possession in the aftermath of Sigurdsson's penalty. That tactic didn't last long, though, as Cahill had his pocket picked by Fur in the worst position possible.
At first glance it looks like a horrendous error from the England defender. However, did Fur clip Cahill's ankles en route to winning the ball?
Chelsea fans on social media are in no doubt at all...
Chelsea have since gone on to equalise through Diego Costa and, at the time of writing the score is tied at 2-2. Nevertheless, if the west London club aren't able to leave Wales with all three points you can be sure that Mr. Marriner will be public enemy number one for the next few weeks at least.
