Arsenal goalkeeper Petr Cech could be out of action for up to three weeks after the veteran shot-stopper suffered an injury during the Gunners’ 2-0 victory over Watford at the Emirates Stadium on Saturday evening.
The 36-year-old lasted for just 45 minutes before he was replaced by summer signing Bernd Leno.
It was the German international star’s first league appearance since his multi-million pounds move from Bundesliga outfit Bayer Leverkusen.
Petr Cech sustained a hamstring injury while he was trying to take a goal kick just before the halftime interval.
The prognosis on his injury was provided by Arsenal manager Unai Emery during his post-match press conference.
According to him, Cech will be out for between two and three weeks with muscular hamstring injury.
In the absence of the former Czech international, Arsenal scored two goals in the last ten minutes to secure a vital win in their London Derby clash with the Hornets.
Watford defender Craig Cathcart diverted substitute Alex Iwobi’s cross into the net under pressure from French striker Alexandre Lacazette to give Arsenal the lead on 81 minutes.
Lacazette also played a part in the second goal two minutes later.
Mesut Ozil converted his right wing cross to wrap up the win for Unai Emery’s men.
