The clash of the round in the Champions League this week could take place in Naples on Wednesday, when in-form Serie A table toppers Napoli host their German counterparts, Borussia Dortmund.

Napoli manager Rafa Benitez won the competition with Liverpool, and his new players in Italy are brimming with confidence, thanks to the changes he has made that have garnered immediate success.

Slovakian midfielder, Marek Hamsik, has been central to Rafa’s tinkering at Napoli, scoring goals for fun, and he cannot praise the Spaniard’s methods highly enough.

"I want to score 20 goals (this season) ... I feel great playing in this system. In only two months you can see the results of the work Benitez has done," Hamsik told La Gazzetta Dello Sport ahead of the Dortmund showdown.

"It's been a radical change with Benitez.

“We keep possession of the ball more and we're more aggressive, we don't wait for the opposition any more, instead we attack them."

Dortmund meanwhile, will enter the intimidating Estadio San Paolo on a high themselves.

They have started the Bundesliga season on fire, and their effervescent 6-2 mauling of Hamburg at the weekend was symptomatic of their ominous form.

Manager Jurgen Klopp’s pedigree rises season by season, and his swashbuckling, carefree style is an intriguing counterpoint to Benitez’s studious pragmatism.

Klopp is rightly in good spirits thanks to the spectacular goalscoring form of his hungry charges.

"That was amazing," he told reporters after Dortmund’s humiliation of Hamburg.

"It was spectacular how the boys played up front and it was pure fun watching them." 

"We are ready for Napoli," Klopp added.

"It is a completely different competition from the Bundesliga and they will be a very tough nut to crack."
