Liverpool fans were left frustrated with referee Stuart Attwell despite beating Aston Villa 1-0 on Saturday afternoon.
The home side had three penalty shouts turned down in the opening 45 minutes at Anfield, first for a tug on Sadio Mane followed by challenges on Andy Robertson.
Jurgen Klopp, as well as Pepijn Lijnders, vented their frustrations on the touchline and Robertson was also in deep conversation with the referee as the teams left the pitch at half-time.
In the early stages of the second-half, supporters became even more aggrieved as the visitor's time wasting went unpunished.

Fabinho's wife, Rebeca Tavares, was among those to share their annoyance on social media as she posted a tweet: "Come on REF, are you here?"
It wasn't until the 65th minute that Liverpool's pressure paid off and a decision went in their favour.
Attwell deemed Mohamed Salah was fouled by Tyrone Mings in the box and the Egyptian slotted home to give the Reds a deserved lead.
Steven Gerrard's side had a penalty shout of their own turned down late on following a mistake from Alisson Becker.
The Brazilian's attempted clearance bounced off Joel Matip and into the path of Danny Ings, but Alisson was quick to relieve the danger, brining down Ings in the process.
