Naby Keita's season at Liverpool could be over.

The Guinea international was substituted midway through the first half of the Reds' 3-0 defeat at Barcelona and is now expected to be out for at least a month, reports The Sun.

The Anfield club are still assessing the full extent of the damage to the midfielder, who could potentially be fit for the Champions League final should Jurgen Klopp's side somehow overcome Barca in the return leg.

Liverpool have yet to release an official statement but the former RB Leipzig star will miss the remaining Premier League matches against Newcastle and Wolves.
