Sim warning on Gunners’ arch-enemy

DIEGO SIMEONE has warned Arsenal: Diego Costa is coming to make you suffer again.

Costa (top right) has recovered sufficiently from a hamstring injury to travel to London.

And the fiery frontman’s potential involvement is bad news for the Gunners as he was their worst nightmare during his time at Chelsea.

Asked if he included Costa to intimidate Arsenal or give his own squad a psychological boost, boss Simeone said: “Knowing Diego Costa, I think all of those apply to him.

“Both in England and in Spain, many teams have suffered at the hands of Costa. Not just Arsenal.

“He will either play from the start or from the bench.”
