Liverpool’s £53 million move for Lyon midfielder Nabil Fekir is in doubt after the club hesitated on concluding the deal after his medical.

Fekir was due to be confirmed as Liverpool’s latest signing on Friday. A deal was agreed between the clubs, as were personal terms with the player, and members of the Anfield medical department have spent the last two days in France to oversee what were presumed the final formalities.

Instead of the anticipated arrival of a club statement confirming the latest transfer coup, enough concerns have materialised over the last 24 hours to ensure the signing has not gone ahead as planned.

Liverpool are offering no indication as to the nature of the problem.

Fekir sustained a serious injury to his right knee when playing for France three years ago. It is unclear at this stage if Liverpool’s caution is in any way related to this past injury problem.
