Arsene Wenger believes the Emirates Cup will provide his squad with the perfect pre-season preparation.

Porto and Galatasaray both won their respective leagues last season, while Napoli finished as runners-up in Serie A. All four teams will compete in the Champions League this term

Arsenal begin the weekend with a clash against Napoli and Wenger is aware of the attacking threat Rafael Benitez’s side will pose.

"[Napoli] have some dangerous players up front because they bought Higuain and they have Hamsik. They are very dangerous on the flanks" Arsene Wenger

“Napoli is a team who in the last three years have been very consistent at the top level in Italy,” the boss said.

“They finished second last year. Of course they lost Cavani but they still have some dangerous players up front because they bought Higuain and they have Hamsik. They are very dangerous on the flanks so it’s a very interesting game for us.”

Arsenal close the tournament with a game against Galatasaray on Sunday afternoon. Fatih Terim’s squad include the likes of Wesley Sneijder and Didier Drogba and Wenger is looking forward to another tough test.

“They are the most popular team in Turkey,” he said. “They have players who of course we know well here like Drogba and Altintop.

“They have a big potential now financially. They also have Eboue who will come back, it will be interesting to see him again. The did very well in the Champions League last [season].”

Arsenal will not face Porto over the weekend but Wenger says he respects the astute way the Portuguese side operate in the transfer market.

"They have invested a lot of money in young players, contrary to what many people think," he said. "They are active on the South American market and they sell well. We have a big respect for Porto."
