John Terry was less than pleased with referee Anthony Taylor's performance during Chelsea's FA Cup final defeat against Arsenal.
The Blues's hopes of adding a trophy to a top-four finish in the Premier League were ended by their north London rivals on Saturday afternoon.
And this was after taking the lead at Wembley thanks to Christian Pulisic's early goal, but the Gunners completed the comeback with a Pierre-Emerick Aubameyang double, the first of which was from the penalty spot.
Then after losing Pulisic to injury at the beginning of the second half, the Arsenal captain put his side ahead with a dinked finish over Willy Caballero.
To make matters worse, Mateo Kovacic was given his marching orders as he was adjudged to have fouled Granit Xhaka whilst already on a yellow card.
It's those two decisions which Blues legend Terry was not happy about.
Taking to Instagram, the former Blues captain posted a message via his Stories - accompanied with an angry face emoji - which reads:
"Never a second yellow, and surely that was a foul on Christensen on the build-up to the goal?"

Terry's thoughts have been echoed by the current Chelsea captain Cesar Azpilicueta
Although, the Spaniard admits the Blues must also look at themselves for failing to beat Arsenal.
"A lot of times there were 50/50s (that went in Arsenal’s favour) and we had the same in 2017 but we have to look further than this," he told the Chelsea club website.
"We have to look at ourselves.
"We know two weeks ago when we played against Man United, we really controlled it.
"We played our game, we were on top of them against a very good side but today we couldn’t do it for 90 minutes and, in the end, that makes the difference."
