Pardew was delighted to have finally landed a man the club had been chasing since January, when they tried to sign him as a replacement for Yohan Cabaye.
Indeed, the 52-year-old included himself in a vote of thanks he extended to owner Mike Ashley, managing director Lee Charnley and chief scout Graham Carr for eventually getting the deal done.
Pardew said: "I'd like to pay tribute to my staff, in particular Graham, myself, Lee and Mike and everyone on the board who worked really hard for this one because he's a player we think is important.
"Obviously, that's represented in the fee and represented in his commitment to us as well.
"I am just looking forward to seeing an exciting talent in the team and someone who can open the door.
"Of course, he's a player who has been on our radar for a while. It's a marquee signing for us.
"He represents all Newcastle fans love in a player. He has real flair, real hard work, commitment. But he is going to bring a talent to St James' Park that I hope our fans are going to enjoy.
"He's got great ideas when the ball comes to him and, along with [former Ajax midfielder] Siem [de Jong], is going to improve an area where we definitely needed some help.
"It's part of a rebuilding process, and a big part of it."
