Super Eagles midfielder Mikel Obi has lashed out at the referee for Chelsea's 3-1 home defeat to Liverpool on Saturday.
Mikel played 70 minutes and was given a yellow card, but feels the Blues were not fairly treated by referee Mark Clattenburg.
"We knew it was going to be a difficult game but we started well and it was a good performance," he told Chelsea's official website on Monday.
"We got the goal and if we went into the break 1-0 up it would have been much easier but the referee played two minutes and 30 seconds [stoppage time] and if we'd played the exact minutes we would have gone in at 1-0.
"Then the referee gave me a yellow card for my first foul and just after that Lucas committed a foul – for me and for everyone else it should have been a [second] yellow card."
Chelsea are currently 15th in the Premier League table, with 11 points from 11 matches.
