Steve Clarke wasn’t happy with the performance of referee Steven McLean in Kilmarnock’s 2-1 defeat to Hearts.
The Killie manager felt that McLean had allowed the Tynecastle side to get away with too many fouls, and didn’t book players quickly enough.
“If you leave all your yellow cards until later stages, you get a lot of breaks in the play towards the end of the game and it suits Hearts” Clarke told BBC Sport.
Clarke was also unhappy with the second Hearts goal scored by Steven Naismith.
“It was a foul for the free kick as well because Naismith blocks off Chris Burke, who is trying to cover the outside of the wall”.
The defeat saw Kilmarnock fail to move up to second place in the Scottish Premiership table.
They currently sit six points behind leaders Celtic, who could go nine points clear with a win over St Johnstone on Sunday.
Despite the loss to Hearts, Kilmarnock have still had a very good season.
They are still well-placed to qualify for Europe, which will be their best league finish for years.
In the Scottish Cup they face a huge fifth round tie against Rangers at Rugby Park.
It will be interesting to see if Clarke is still at Kilmarnock next season.
He is bound to be in demand after the job he has done so far at Rugby Park.
