Former Arsenal striker Robin van Persie believes Unai Emery is failing to connect with his players.

After the Gunners struggled to beat Vitoria on Thursday, van Persie said Emery hadn't built strong enough relationships with his squad.

"I don't think so. I don't think that Emery really connects with his players," he said on BT Sport.

"I think they're still weak on set pieces, that was back in my time still a problem to be honest. Everyone should feel responsible. Do you play zone or do you play man on man?

"I think when you're struggling you should play man on man, because then you just pick your man then you are responsible for your man. It's a one on one fight.

"Last weekend they again conceded from a corner kick. I said it a couple of weeks ago as well, Arsenal lose 12-15 points per season by set pieces and that should stop. You have to sort it out, you have to find away.

"You can see some players, and it's not honest to judge the coach based on tonight, it's based on the last couple of months and even the year before. As a player, you want to have that feeling you have to sprint back, and now you see a couple of players that jog back. There's a danger there.

"If you have a very strong coach, and you're in midfield, and you see there is danger somewhere, you will sprint for your life, because you know if you don't do it you get punished."
