New Juventus coach Gigi del Neri says he can play 4-3-3 if needed.
Del Neri's famous 4-4-2 system is seen as the end of the road for players like Diego at Juve.
"It is not true that I always play 4-4-2, I also like 4-3-3," said Del Neri.
"When at Roma I used a trident, but also had the trequartista behind a lone striker like in Bergamo or Genoa. I have always been open to new ideas.
"A tactician always needs to consider the quality and talent at his disposal in order to make the most of his players.
"We will start with four at the back that is for sure. Then we will change according to our rivals.
"Inter have created a 4-2-3-1 which has been fundamental to counter-attack with great speed and that can be seen as an example."
