Mesut Ozil says Arsenal are much stronger this season thanks to their summer market work.

Arsene Wenger spent almost £90million in the last transfer window acquiring Rob Holding, Lucas Perez, Granit Xhaka and Shkodran Mustafi.

“They've been fully integrated from the first day," Ozil said. “They are guys who just get on with everyone and bring positive energy to the team. I've known Shkodran from the German national team and we spoke a lot about this club before his transfer. I can say a lot about Xhaka, too.

“He's a really positive guy, very down to Earth and we've already seen that he can score goals. He's got a left hammer! Musti can help us a lot, too. He's got plenty of defensive quality and it is clear both players have strengthened the squad.

“He had a few questions about the team, the manager and the city. We spoke about things and I was pleased that he eventually decided to move here.

“I was pleased to help him because I've been here for a few years and he asked a few questions that I could answer because I'm here every day. I could tell him how things are. It was good for him to decide that he could further develop here and that's what he's doing."
