"It's going to be thrilling. Obviously, I will be at the Johan Cruijff Arena, but don't ask me who I will support. I will watch the game as a neutral fan and it doesn't often happen when I watch Ajax," Krol told La Gazzetta dello Sport.
“I like the Azzurri, they prove solidity week in, week out and it wasn't something to take for granted after all the changes this summer.
“I watch Serie A games, but also other clubs in Europe and I can say that no team plays better football than Napoli in Italy and abroad. They were exciting to watch in the past, but now there is something special. A winning attitude that I had never seen in the past."
