Arsenal goalkeeper Emi Martinez revealed he was left "devastated" by the worrying injury to Bernd Leno as Arsenal slumped to a 2-1 defeat to Brighton on Saturday.
Leno - who has been an ever-present in the Arsenal backline following his arrival from Bayer Leverkusen in 2018 - landed awkwardly following a collision with eventual match-winner Neal Maupay.
Martinez was brought on to replace his injured team-mate for his first Premier League appearance in three years.
He was unable to prevent late goals from Lewis Dunk and Maupay, however, as Arsenal lost for the second time in four days.
"In the goalkeepers' union, you don't want the other goalies to get injured because it can happen to anyone," Martinez told Arsenal's official website.
"We train every day together, we support each other, we're really close, we even have a WhatsApp group for just me, Bernd and Matt - it is devastating to be honest.
"I wish him a speedy recovery and if he needs the rest of the season, me and Matt will try to do a good job in the Premier League and try to cover him as much possible.
"The last time [I played] in the Premier League was three years ago," he added. "But I wasn't thinking about it when I just came on.
"I made a save straight afterwards. I am so disappointed for the result, I thought we deserved to be 2-0 or 3-0 up. But you just take it and learn from it."
