Sevilla boss Julen Lopetegui has delivered his initial verdict after Manchester United loanee Anthony Martial was forced off inside half an hour on Sunday.

Martial required lengthy treatment after going down holding his left leg with reports from Spain suggesting a hamstring issue in what was his fourth game since completing his temporary move.
