Roberto Firmino has reportedly emerged as a fitness doubt for Liverpool's Champions League encounter with Bayern Munich on Tuesday evening.

Firmino has been a regular in Jurgen Klopp's starting lineup this season, with 11 goals and four assists coming from 32 outings in the Premier League and Europe this season.

However, according to the Liverpool Echo, Firmino may miss the clash with the German champions having picked up a virus.

The 27-year-old is a likely starter should he recover in time for the game at Anfield, but his absence would be regarded as a huge blow by Klopp.

Liverpool are unlikely to take any risks with the Brazilian due to make the trip to Manchester United at the weekend.
