Speaking to Prime Casino, Gallas said: "How many more years will the players wait? Two years ago, they were so close. Last year, close again. This year it didn’t happen again, and they actually fell back a little, they got worse. They were perhaps focusing too much on another thing or looking to the next campaign again. The problem is always the same with Arsenal. They need the right players. They can’t always have excuses, blaming one player or another being injured. That happens every year, it’s not a new problem, it doesn’t only happen to them. So they need a big squad, and to do that you actually have to buy quality players. When you have a big squad full of talent, things are different.
"It’s difficult to manage a squad like that, so the question is whether Arteta has the skill to do it. But even if they buy a striker, they’re still vulnerable if Bukayo Saka is injured, because there’s nobody who can step in with international experience. Someone who might be a different type of player but who is still effective. They’re short in more areas than just the striker. Even at the back, they’re a bit short if they want to be confident of a title challenge."
