On his expectations for Arsenal's season, Gallas said: "To be honest, the last two years my expectations were to see Arsenal win the Premier League because for me, other clubs were underperforming and they had the chance.
"And what I expect from them as well is to have more personality, more character on the pitch. I really want to see players fighting in a positive way. Because we know the season is going to be long. We know sometimes there will be trouble against some teams and sometimes you have to show your character.
"Not just some of the players, but all of them. We know at the back they have Gabriel who can do that, and we know Declan Rice can be that guy too, but more need to step up. I want to see others who take responsibility and shout at their team-mates if they’re not doing enough."
When asked if Arsenal need to win a major trophy this season, he said: "Arteta doesn’t have five more years! Listen, with that squad, we are not talking about winning the FA Cup, the Carabao Cup. We are talking about the Premier League. We are talking about the Champions League. Nothing else.
"If you asked the Arsenal fans to choose winning the Premier League and the Champions League, I think they would choose the Premier League.
"That's why Arteta is going to have a lot of pressure on his shoulders, and as you said, he can't hide from anything. If he doesn’t win either trophy, he’s the one to blame. We have been waiting to see if he’s a manager who can win - now’s the time."
