Speaking after the defeat, Middlesbrough manager Neil Warnock tore into the quality of officiating throughout the game, and claimed: "I’m just really disappointed, I thought the lads played some good football and I thought we were the best side on the pitch.
“I didn’t see them have many chances at all and we’ve been let down by poor officials really nothing else.”
“I think with ten minutes gone, (Ryan) Manning took (Anfernee) Dijksteel out and not one of the four officials saw it, and it ended up him coming off injured. He’s deliberately kicked out at him and has taken him down.
“(Marc) Bola’s goal is a certain goal, it’s either a penalty to us or a certain goal, but because the kid dives he gives it as if they’re diving.
