When Chelsea decided to buy Diego Costa and sell Romelu Lukaku in the summer of 2014, the theory was that one wasn’t good enough and the other represented an upgrade.

Over the course of a season or two, that judgement may yet prove true. Costa can be among the best.

Yet at Goodison Park, Chelsea owner Roman Abramovich must have been reflecting on whether the trade was worth the trouble it has brought.
For one of those men produced a defining performance, scoring two goals, one of them quite outstanding, as he thrust aside multiple Chelsea defenders to finish sublimely.

The other striker is embroiled in a fresh controversy, his jaws appearing to close around the neck of Gareth Barry in a fashion made familiar by Luis Suarez. The fact that Costa seemed to pull back from the apparent intent to bite at the last moment may yet save him.

Yet there is additional footage available that suggests otherwise or contrary evidence from Gareth Barry – and Roberto Martinez indicated that Barry did not seem to think he had been bitten – then a lengthy ban awaits.

Roberto Martinez seemed to think it was all part of the magic of the FA Cup. ‘Diego Costa has a fighting spirit,’ he said. ‘I don’t think it was much. Whatever happens with Diego Costa, I think we should see it as what we want to see in a cup game, real emotions. And I’m sure the players will have shaken it off at the end of the game and there is nothing to look back at.’
