The midfielder completed a move from Swansea City this weekend.
Steve McClaren’s side completed a £12 million move for the Swansea midfielder on Tuesday, as they look to add talent in January to try and avoid relegation this season.
It was a change in transfer tact for the Magpies, who have mostly bought from across Europe in recent seasons, with a number of signings from France in particular.
Only the firmest of fans will have been previously aware of several of them, with most having arrived at St James Park as unknown quantities.
Shelvey is different though, with him having been around in the Premier League for several years, and Jenas says that is good for the fans.
“I think more than anything it will be fantastic for the fans to relate to a player they know,” he told BT Sport.
“He’s an exciting prospect. Once he gets his head right, he can bring a lot to the team at Newcastle United.”
While it is good for Newcastle fans to have a player they know in the squad, it is arguably not the reason he has been brought in.
Steve McClaren will instead be hoping he can add some much needed creativity with the likes of Jack Colback and Cheick Tiote not the most creative of forces in central midfield.
Shelvey will also be keen to impress, with a place in England’s squad for Euro 2016 very much up for grabs if he can discover his form from earlier in the campaign once more.
