Newcastle have signed French full-back Mathieu Debuchy for an undisclosed fee from Lille.
The 27-year-old, capped 11 times for Les Bleus, has penned a five-and-a-half-year contract with the Magpies - much to manager Alan Pardew's delight.
"We are absolutely delighted to have finally secured the signature of Mathieu," said Pardew.
"It's no secret we have been trailing him for some time now and to have reached this point fills me with great excitement and anticipation in respect of what he will be able to offer the team.
"At the same time, it's a huge relief to actually have him with us now.
"He is an established top international player and it is a real coup for this club that we now have him at St James' Park.
"Mathieu will add real quality to our team in terms of his ability, character and experience, and I am sure he will quickly become a firm favourite among our fans too."
Debuchy is eager to add value on Tyneside.
"It is great to become a Newcastle United player," he said.
"After many great years at Lille, I felt I was ready for a new challenge, and cannot wait to play for such a big club in the best league in the world.
"I hope I can bring something fresh to the team and help us get up to the highest possible position in the Premier League this season. I will give everything for this club."
