Aston Villa boss Unai Emery has been left sweating on an injury to Emiliano Martinez.

The Villans were caught by Chelsea (2-2) yesterday, but remain in good position to finish in the top 4.

If the result is frustrating, Emery also suffered a hard blow, the loss of his goalkeeper Martinez to injury.

The Argentina international was replaced by Robin Olsen after not returning from the locker room in the second half.

The nature of his injury is not yet known, but his absence could prove huge in the final sprint in the Premier League .
