Newcastle United have completed the signing of Jonjo Shelvey from Swansea City, but could not register the midfielder in time for their exciting 3-3 draw against Manchester United. The England international is likely to play a part in Newcastle's game against West Ham next weekend, as the Magpies look to get themselves out of the relegation zone.

Shelvey would be Newcastle's second signing in 24 hours after they completed the transfer of Henri Saivet from Bordeaux, as Steve McClaren looks to close the gap between themselves and the clubs around them who are struggling to avoid relegation. The midfielder found himself an isolated figure at the Liberty Stadium, where he recently got into an altercation with fans and was warned for his behaviour by the club.

Newcastle had been scouting the player for a long time and finally managed to convince the Magpies to close the deal for a fee expected to be around £12m ($17m), The Guardian reported. Shelvey has made 126 league appearances for Liverpool and Swansea combined and will add some much needed flair and experience to the Newcastle midfield.

"I'm very excited to be here. I'm so glad that it's finally done," Shelvey told Newcastle's official website. "I drove up through the night to be here so it's been a manic 24 hours but it's all been worth it to come here and play for this great club."

Meanwhile, McClaren has cut a satisfied figure with the transfer and expects Shelvey to improve the Newcastle team as they venture into the business end of the season.

"I'm delighted to welcome Jonjo to Newcastle United. He has great experience for a young English central midfielder and is a current England international, so I'm certain he will be a great addition to the squad. He is a player we have admired for some time and we're very pleased that we've now been able to bring him here," McClaren said.
