Villarreal coach Juan Carlos Garrido described Napoli as the best team in Italy ahead of the pair's clash in the Champions League here on Tuesday.
Napoli have failed to win or even score in either of their last two league games while Villarreal have won only one out of five La Liga encounters this season.
But Garrido believes both teams have the capability to do much better than that this term.
And he is not going to take Napoli lightly.
"Already last year they showed what a great team they are," he said.
"At times this year they could have done better or worse but for me they're the most in form team at the moment.
"AC Milan, Inter Milan, Juventus and Napoli are the best teams in Italy but I think at this time Napoli are in the best form.
"They have fast players, they play with intensity.
"But in the Champions League it's fundamental that you get points to qualify for the next round.
"We will try to take some points tomorrow (Tuesday), we'll give our best and we'll try to play in the best way possible."
Garrido agreed that Bayern Munich are the best team in Group A but claimed all three of the Germans' opponents, including Manchester City, are capable of beating them.
"It's a very interesting group, perhaps the most interesting in the Champions League," he said.
"There are four very good teams who are at the top European level.
"It's true that Bayern are one of the best teams in Europe and they're in very good form but we're three very good teams and we could all cause a surprise."
The coach admitted he didn't know if Italy international forward and former Napoli target Giuseppe Rossi would be fit for the game.
And he denied that either his side or Napoli were in a crisis at the moment, despite both recording some unimpressive results recently.
"Crises pass very quickly, as quickly as they can arrive, they can end immediately too," he said.
"It's the beginning of the season, we've just started going in search of our objectives.
"Last season we both did very well in the league and got good results in Europe.
"Neither of us are in crisis. In two or three months you'll see the true worth of both of these teams."
The Spaniards' Colombia defender Cristian Zapata spent six years playing in Italy and he knows Napoli well.
He says his side need to watch out for the Italians' attacking triumvirate.
"(Ezequiel) Lavezzi, (Edinson) Cavani and (Marek) Hamsik, they're the three forwards and they're very dangerous, they're the ones we fear the most in this team," he said
"It will be a good game, there's a special atmosphere given the fans they have here.
"Napoli will go forward to attack, they'll try to win and they'll play with intensity.
"We have to have confidence, we have to play our football and try to get the result we expect."
