Nuno Espirito Santo says it is ‘obvious’ that concussion substitutes should be introduced in the Premier League following the injury to Wolves star Raul Jimenez.
Jimenez suffered a fractured skull after a clash of heads with David Luiz, five minutes into Wolves’ 2-1 win over Arsenal last Sunday.
The forward required 10 minutes of treatment on the pitch before being stretchered off and taken straight to hospital. Luiz, however, was bandaged up and sent back on for the rest of the half, with Mikel Arteta later saying the Brazilian had been “uncomfortable” after the collision.
