Birmingham City boss Lee Clark was unhappy with referee James Linington after allegedly mocking captain Paul Robinson.
“There was an incident involving Danny Ings and Paul Robinson. I thought it was a foul by Ings.
“They scored from the resultant free kick. Paul remonstrated with the referee, who gave Paul a yellow card, but he mocked him about the scoreline at the time. This is totally unacceptable.
“There seemed a bit of an arrogance among the officials. This is people’s livelihoods.”
