Kenedy and Dubravka have both impressed in Tyneside following their loan moves from Chelsea and Sparta Prague respectively in January.
In fact, their performances on the wing and between the sticks helped Newcastle to go on a four-game winning streak in the Premier League to ensure the club's survival, leading Benitez hopeful of making their deals permanent.
He told reporters ahead of Wednesday's league match against Tottenham: "Kenedy is a player that we like".
"He has been doing really well and we have to wait and come back and talk with Chelsea about his future.
"Dubravka is an easy one because we have the option and it's not a secret that we are happy with him, so we will see how we finish but that is an easy one."
