He is ready to face Manchester United at St James' Park on Wednesday, in a rematch of his debut fixture last season when he turned in a memorable performance to help United win 1-0.
Dubravka has now racked up 32 games as Benitez's No.1, and kept a remarkable 10 cleans sheets in a side that's been constantly fighting relegation.
Benitez said: “If he continues to do well, it is good for us. If he attracts interest, it means he is doing well, positive, doing well — but also negative, because it means they are attacking a lot!
“He's an important player for us; not just because of the saves that he is making, but because of his character and his attitude, too. He is very professional, he is very positive - so he's someone that is always good for any team and is a key voice in the dressing room."
“It's true [he is so consistent he can be taken for granted]. It's not easy to have a very good keeper, but when you have one them it's important."
