Talks have taken place at Arsenal about the threat posed by gangs targeting footballers after Mesut Ozil and Sead Kolasinac had to fight off knife-wielding men, according to academy manager Per Mertesacker.
In an apparent attempted carjacking caught on camera in July, Kolasinac jumped out of a vehicle to confront masked aggressors, who had pulled alongside Ozil's vehicle on mopeds.
A separate incident led to two men being charged with a public order offence outside Ozil's house in north London.
"There was a big discussion around gangs in London and the security matters," Mertesacker told AP.
"The major part of what car you drive, what you wear in terms of your jewellery.
"So you need to be risk-aware in those days that anything can happen at any time. And these are examples you are trying to avoid."
Concerns about their safety led to Ozil and Kolasinac missing games.
"Once these things happen it is an eye opener to where the world is in terms of poverty around London and how can we make sure that it is not going to happen again," Mertesacker said.
Especially as Mertesacker, the Arsenal captain before assuming the academy role two years ago, does not want players to become even more distant from fans.
"When these things happen, the more fences, the more security guys and the more gates will eventually happen," he said.
"And that would be very, very sad."
