Napoli president Aurelio de Laurentiis is a big fan of the Borussia Dortmund model.

De Laurentiis feels Napoli's approach is similar to BVB.

"There are two trends. Borussia adopt my philosophy, which is that it's better to grow champions in house. It takes patience and you must resist the pressure.

"Bayern Munich on the other hand take all the best they can get their hands on and change every two or three years to keep motivation fresh. Now we'll see Pep Guardiola at Bayern Munich without the Barcelona academy behind him."
