Roberto Firmino struggled to make an impact against Manchester United – and Liverpool fans were disappointed with his performance on Twitter.

Liverpool were held to a 0-0 draw at Anfield on Monday night and the forward was substituted off in the closing stages of the match.

The forward was presented with the best chance of the match, when he was played through on goal by teammate Philippe Coutinho.

Firmino was baring down on David De Gea’s goal but United defender Antonio Valencia tracked back and produced a phenomenal challenge.

The result leaves Liverpool fourth in the Premier League table and two points adrift of league leaders Manchester City.

Liverpool supporters expressed their disappointment with Firmino’s display and one fan claimed he looked visibly tired.

Here is a selection of their messages on Twitter:

Firmino, 25, has been a regular feature in Jurgen Klopp’s this side and has operated as the central striker.

He was pushed out wide against United to accommodate centre forward Daniel Sturridge, but he was taken off after just 60 minutes after struggling to trouble the defence.

The Brazilian international is expected to keep his place ahead of Sturridge after impressing in the early stages of the season.

Firmino has now made 10 appearances for the Merseyside club, scoring four goal and supplying three assists in the process.
