Similar to Batshuayi, Perez hasn't been able to find his way into the Arsenal team because of the fine form of his teammates. Arsenal's regular starting centre forward last season - Olivier Giroud - has also been a victim of Alexis Sanchez's good start to life as the club's main striker, meaning the Spaniard may have to await his turn and impress when given the opportunity.
The 27-year-old did score a tidy brace against Nottingham Forest in the EFL Cup but managed to pick up an injury shortly after, meaning his opportunities have been limited so far.
