Lucas Digne faces up to a month out of action after suffering a hamstring injury during Aston Villa's 3-2 defeat to Manchester United on Boxing Day. The French international sustained the injury sliding to block Alejandro Garnacho's disallowed goal in the second half, before the hosts rallied from 2-0 down to beat Villa."Lucas Digne is injured and he will be out for the tram for some weeks," said head coach Unai Emery, speaking before Burnley's trip to Villa on New Years' Eve. "We are playing very good, but we have to try now and replace him with Moreno after a long injury. I think Moreno is ready and it will be 20 to 25 days for Digne."Meanwhile, deputy goalkeeper Robin Olsen remains unavailable and Pau Torres, who returned to the bench against Manchester United, is still not fully fit and unlikely to start against Burnley. Boubacar Kamara will serve the third match of his suspension but Matty Cash will return to the squad after a one game ban h
