Liverpool midfielder Naby Keita returned from Naples independently from his team mates having undergone two scans to ensure he did not suffer spinal damage in the Champions League defeat.

Keita underwent both a magnetic resonance imaging (MRI) and CAT scan after being forced off in the 16thminute of the 1-0 defeat.

Earlier claims doctors were testing Keita for a possible heart issue were dismissed by his club and Italian medics. “Keita's just been discharged,” Ciro Mauro of the Cardarelli hospital's cardiology unit told Naples' Radio Marte.

“He's got a flight to Liverpool at 2pm. He didn't have a cardiologic problem, it was a strong back trauma. He had an MRI and CAT scan to rule out any problems to his spine.

“It is not related to a cardiovascular problem. The player was serene when he left and the Naples doctors have given him a good bill of health.”
