Arsenal manager Mikel Arteta has claimed it is too early to know the severity of Gabriel Martinelli's injury.
Martinelli was substituted inside the opening 20 minutes of Arsenal's 3-0 defeat to Brighton with what looked like a suspected ankle injury. The Gunners' medical team had been keeping an eye on Martinelli just minutes before he was withdrawn after he needed treatment following a strong challenge from Arsenal target Moises Caicedo.
The 21-year-old's ankle appeared to get trapped underneath the sliding leg of the Ecuadorian midfielder and he was therefore unable to continue, with Leandro Trossard brought on to replace him against his former club. Martinelli headed straight down the tunnel after his withdrawal and was then spotted post-match walking round the Emirates turf in a protective boot.
