Villa keeper Martinez sustained hand injury against Chelsea

Aston Villa's Argentine goalkeeper Emiliano Martinez was substituted at half-time in his side's clash with Chelsea after picking up an injury during the first half.
The Villa goalkeeper asked his manager, Unai Emery, for a substitution in the final minutes of the first half, apparently with a hand problem after a collision with Nico Jackson.
The Argentine held on until the end of the first half and, at half-time, was replaced by Roger Olsen as his side trailed 2-0 with goals from Nico Jackson and Enzo Fernandez.
