Schar admitted that fan backlash is the “worst thing” that can happen to a footballer after Xhaka was booed off by his owen supporters against Crystal Palace., reports The Sun.
The 27-year-old said: “I played with him for years and I know how he is as a person.
“He’s doing everything for Arsenal, which is why he’s captain. He’s a very good guy and people aren’t seeing this.
“I will see him in a couple of weeks with the international team and I’ll give him a hug.
“It’s very hard for a player when your own fans are against you.
“Then you do something emotional that people don’t understand.
“It would be a very difficult situation for any player to have to deal with that.
“To have that from your own fans is the worst thing that can happen to you.
“Nobody wants to see things like this. I’m happy that this has never happened to me.”
Schar says Xhaka is worshipped back home after helping Switzerland into the last 16 of last year’s World Cup.
He added: “He has a much better standing in Switzerland.
“It’s seen as a big thing that he’s captain of both his country and Arsenal.
“He’s doing a great job for us. I know how he is and how he feels.
“I can really understand him and I’m feeling for him.”
