Aston Villa boss Paul Lambert has suggested Chelsea would have been awarded a penalty if an incident similar to John Terry's apparent handball had occurred in the home team's box in Wednesday night's Barclays Premier League match at Stamford Bridge.
Lambert felt his side had been denied a legitimate spot-kick in their 2-1 defeat to the Blues when Terry appeared to block Gabriel Agbonlahor's header with his arm in the area late on.
The Scot also thought Branislav Ivanovic should have been sent off for catching Christian Benteke with an arm - the defender instead received a booking, before going on to score the winning goal.
Asked on Thursday morning about Kevin Friend, the referee for the game, Lambert said: "I spoke to Kevin afterwards, and obviously what is said in there stays in there. But I didn't need to speak to him really.
"It was a clear handball.
"It's a stonewaller, a clear penalty. I don't care what anyone says, that is a penalty.
"Gabby has won the header and it has hit John's hand. I'm pretty sure if it had been down the other end, it would have been given."
Lambert and Chelsea manager Jose Mourinho were engaged in what appeared to be some heated arguments by the touchline during the contest.
But Lambert insists the technical area exchanges were predominantly "banter".
He said: "I was calm last night."
