Robson can't digest Rennie decision
Robson was fuming at Rennie's decision to caution talismanic captain Alan Shearer for dissent - a yellow card which rules the striker out of the January trip to West Ham under the totting up procedure.
Shearer was booked after complaining about Rennie's disciplining of Lomano Lua Lua for diving and Robson was baffled by both yellow cards.
"Shearer said to the referee 'before you take a card, go and have a word with Whitlow'. I have to hold up my hands to Whitlow. He told the referee he had fouled him, he had tripped Lua Lua," stated Robson.
"But he still gave him a yellow card for diving. Shearer, speaking plainly, got a yellow card as well.
"Can you explain that to me? Because I will be explaining it to the FA and the Premier League.
"I will now lose Shearer for the West Ham match after his fifth yellow card.
"We got two yellow cards which I find is absolutely outrageous - but there is nothing we can do about it."
Robson also slammed a section of The Reebok crowd who subjected Shearer to a torrent of abuse.
He added: "I can't understand fans making obscene chants at Alan.
"He is a nice guy, a great professional and he has captained his country."
