Olympiacos manager Zico knows his side will have to be mentally tuned-in on Tuesday night when they take on Arsenal in a "difficult" Champions League encounter.

The 56-year-old has only been in charge at Karaiskakis Stadium for two weeks following the departure of Temuri Ketsbaia. However, he's well prepared for the test against Arsène Wenger's side and knows what his team have to do if they are to have a chance of getting a result against the Gunners.

"We know of the difficulties that playing against Arsenal brings us, especially when they're at home," said the former Brazilian international.

"It's important that we pay them the utmost attention, that we leave no space for them.

"They are a fast team, especially when they attack, and especially on the counter-attack. We will have to concentrate.

"We have to play in a brave way. We must have the mentality that we are equal. On the field it's 11 versus 11, and that is the mentality I want from my players.”

As a player, Zico was at Japanese outfit Kashima when Wenger was manager at Nagoya. Since then he has followed the career of the Frenchman, and says he is an admirer of the way his sides play the game.

"I remember Wenger very well from Japan," said Zico. "I admire the offensive way he makes his team play.

"I have followed his career at Arsenal and I like the way he always makes the most of the characteristics his players have."

Zico added that he was delighted to see Eduardo fully recover from the broken leg he sustained against Birmingham two seasons ago.

"I am very happy that Eduardo has recovered," said the Olympiacos manager. "He spent three weeks of his recovery in my academy in Brazil and it was very good when we saw him recover the way he did."
