The Italian doctor who treated Liverpool midfielder Naby Keita has given him the all-clear - including rubbishing heart concerns.

Keita was taken to hospital after being carried off during Wednesday's Champions League loss away to Napoli, with Italian media suggesting he had been admitted to the cardiology unit of the Antonio Cardarelli hospital in Naples.

Dr Ciro Mauro, who is director of the cardiology department at the medical facility, is also coordinator of the emergency admissions department and oversaw Keita's treatment.

Speaking to Italian radio, he confirmed Keita was kept in overnight after being submitted for MRI and CAT scans on his spine having appeared to collapse on the pitch at the Stadio San Paolo.

“Keita's just been discharged," Dr Mauro explained on Thursday afternoon. “He got a flight to Liverpool at 2pm. He didn't have a cardiological 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."

Although Dr Mauro – a Napoli fan – joked he wanted to keep the player in hospital for longer.

He said: “We've recommended a long period of recovery so that he won't play in Liverpool-Napoli. We just hope he's not so lively in the return fixture."
