Lucas Perez played 72 minutes against Reading on Tuesday night – and the Arsenal supporters were concerned about their striker.
The forward was forced off in the second-half with a suspected ankle injury and replaced by youngster Chris Willock, who made his second senior appearance.
Arsenal recorded a comfortable 2-0 in the EFL Cup fourth-round and booked their place in the quarter-finals.
Midfielder Alex Oxlade-Chamberlain scored twice either side of half-time to complete a comfortable home victory.
Perez was handed the opportunity to lead the line for the Gunners and failed to prove a serious goal threat while on the pitch.
Arsenal will have to wait to find out the full extent of Perez’s injury and the club’s fans are fearing for the worse.
Here is a selection of their messages on Twitter:
Perez, 28, has endured a frustrating start to his Gunners career since his arrival at the Emirates in the summer.
The striker had now made six appearances for Arsenal and his only goals were a brace against Nottingham Forest in the EFL Cup earlier stages.
Manager Arsene Wenger does have several attacker to choose from and has preferred in-form Sanchez to spearhead the attack at the beginning of the season.
The striker impressed at his former club Deportivo in Spain, scoring 24 goals in just 59 appearances for them, something he will hope to replicate at the Emirates.
