Costa back to spike Gunners

DIEGO COSTA has been included in Atletico Madrid’s squad to face Arsenal tomorrow.

The Gunners’ arch-villain had been expected to miss the first leg of the Europa League semi-final after picking up a hamstring injury in the last round against Sporting.

But Costa – a thorn in Arsenal’s side during his three seasons at Chelsea – could yet prove their undoing in their bid to win a final trophy for Arsene Wenger.

Costa has missed Atletico’s last three matches and boss Diego Simeone had all but ruled him out of this week’s Emirates tie before his squad inclusion was announced.
