Newcastle fans are absolutely desperate for a new centre back signing, after Florian Lejeune suffered a serious knee injury.

Rafael Benitez has weighed in on the speculation surrounding Lejeune’s absence from the pre-season draw with Hull, and it’s very bad news for Newcastle fans.

The Frenchman has reportedly suffered a knee injury, thought the extent of the damage is not yet known.

“The only one (injury) that is a bit more serious could be Lejeune,” said Rafa.

“He has a knee problem that we have to assess in the next couple of days.”

While there is no word about how much time the towering centre back will miss, a “serious knee problem” does not sound good, and fans are now pleading for a new signing.

Chancel Mbemba has left the club, and Fabian Schar is expected to replace the pacey defender, but Lejeune’s injury means the Magpies will probably need another defender as well as Schar.

Jamaal Lascelles was an absolute rock last season, but his best form was undoubtedly thanks to his partnership with Lejeune, and fans are extremely worried.
