Newcastle striker Alexander Isak says he knows the importance of their FA Cup clash with Sunderland.
Isak admits the local Toon players have made clear how big the derby fixture will be.
The Swede told BeinSport: Of course, it's a big game.
"Some of the local lads have told us how much it means for the fans and the city. It's going to be a big day when it comes.
We have to be as focused and prepared as possible. We have all been in teams when there's a derby, I know I have. At every club I've been at, there's been a big derby. I know how important this (will be) for the fans and how much it means to them."
