The midfielder is a January signing from Ligue 1 side Bordeaux.
The Senegalese international completed a move from Ligue 1 side Bordeaux last week, in a deal that has cost Steve McClaren’s side a reported £5 million.
He is not the only new midfielder in the squad; with Jonjo Shelvey having also arrived in a more expensive move from relegation rivals Swansea City.
But whereas Shelvey has been brought in as a creator, which he showed in the 2-1 win over West Ham at the weekend, Saivet says he is bringing some much needed defensive attributes to the side.
“I think for me I can bring a carefree attitude, and some aggression in the tackle in midfield,” he told the Mirror.
“I am a ball player as well and giving passes to Ayoze Perez and Wijnaldum to exploit their talents and bring the best out of them.”
The Newcastle side could certainly do with some defensive steel being added to it, with them enjoying a shocking record so far this season.
They have already conceded 39 goals in 22 games this season, the second worst record in the division behind Sunderland and worse than bottom of the table Aston Villa.
It is clearly an area that needs improving if they are to avoid the drop, and they will be hoping Saivet can help protect that leaky defence in the second half of the campaign.
