Football matches involving Diego Costa are never, ever dull.
The Chelsea striker has a comically short fuse. So short, in fact, that you get the impression he could start a fight in an empty room.
Costa is the type of player that everyone loves to hate. He’s the archetypal pantomime villain. But let’s face it: whether you love him or loathe him, he’s always entertaining.
The Brazil-born Spain international was in top form again during Monday night’s FA Cup clash against Manchester United at Stamford Bridge.
And on this occasion, Marcos Rojo was the unfortunate soul who Costa attempted to antagonise at every available opportunity.
Costa was up to his old tricks v United
That was one moment midway through the second half that wound everyone - with the exception of Chelsea fans, of course - right up.
Costa was tussling with the Argentine defender when he fell to the ground like he’d just been taken out by a sniper in the crowd.
The 28-year-old, who is apparently a lovely guy off the pitch, was blasted on social media for cynically attempting to get Rojo sent off and understandably so.
Costa has clearly learned some English
But minutes later and he had football fans on Twitter in stitches with his amusing comment to the assistant referee.
Costa, again trying to get Rojo in trouble, was furious when the linesman decided not to flag for a Chelsea free-kick.
So he got up and shouted some rather, erm, industrial language - in perfect English, mind you - straight at the lino.
Watch it here…
It doesn’t take a lip-reader to work out what he said.
This is the incident that wound Costa up...
Twitter loved Costa's naughty outburst
Here’s how Twitter reacted to Costa’s outburst….
Costa should have been punished
In all seriousness, Costa really ought to have been punished for saying this to the assistant referee.
Match officials put up with far too much and referee Michael Oliver could - and perhaps should - have taken action against Costa for abusing his colleague.
Chelsea through to the semi-finals
Although it was a frustrating match for Costa, it was Chelsea who march onto the FA Cup semi-finals thanks to N’Golo Kante’s second-half strike.
Antonio Conte’s side will face Tottenham at Wembley Stadium next month, with Arsenal and Manchester City contesting the other semi-final.
