Goal exclusively revealed on Sunday that Pardew was closing in on deals of Remy Cabella, Daryl Janmaat and the French forward, with the former arriving later that day and the full-back undergoing a medical since.

When asked about a potential move for Riviere, Pardew told reporters: "It's another one that we're talking to. He's a player that we have some interest in."
"That's pretty close," he added regarding Janmaat. "But that's as good as I can say at the moment. I've been involved in the [Oldham] game, so I don't know the detail of it."
In addition to the completion of Cabella's move, Newcastle have also brought in Siem de Jong, Ayoze Perez and Jack Colback - the former of which scored on his debut at Boundary Park.
Pardew is keen to further bolster his squad, with Mathieu Debuchy set to complete a move to Arsenal, as he looks to improve upon a disappointing end to last season, which saw the club win just five games in 2014.
He added: "We're being active at the moment, and we need to be. We need to be stronger than we were last year."
