Watford technical director formerly of West Ham, Gianluca Nani has praised Arsenal ahead of the Napoli tie.
Napoli have been warned for tomorrow night: You have to beat one of the top five teams in the world!
Watford technical director Gianluca Nani, a regular pundit in the Italian media, was interviewed ahead of the Champions League tie between Napoli and Arsenal.
Napoli need to beat Arsenal by three clear goals to ensure their own qualification, or hope point-less Marseille get a result against Borussia Dortmund.

Nani, who once held the same post at West Ham United, told Italian radio:
"The Gunners are the first in the Premier League and as a result are among the top five teams in the world. 
"Then it will be for Napoli quite a feat, but they can do it.
"Napoli has great players and an incredible crowd.

They should be very careful in defence, because Arsenal in every play attacks and tries to score goals."

It's a bold statement about Arsenal being in the top five teams in the world - pundit Michael Owen still believes the Gunners will only finish as the fifth best in the Premier League.
But behind Barcelona and Bayern Munich - who Arsenal fans will point out they beat away from home last season - there is arguably little to separate the Gunners from the likes of Real Madrid, Atletico Madrid, PSG or Juventus.
What do you think? Are Arsenal one of the top five teams in the world at the moment?
