When asked if he feels confident that a deal could be completed for Grenier, Pardew told TEAMtalk: "I don't know. We have two days left and we will have to wait and see. I'm obviously hopeful.
"[Grenier] has tremendous creative technical ability and he's a player that Newcastle fans would love to see at the football club. But he's still not our player, so until he is, I will wax lyrical about him then."
Newcastle have completed the loan signing of Luuk de Jong from Borussia Monchengladbach this week.
