Liverpool midfielder Jordan Henderson has urged fans to get behind Lazar Markovic.
The vice-captain has no doubts about the Serb's quality.
"Lazar's a fantastic player who's got great potential," Henderson told liverpoolfc.com.
"In training we see the quality of the players that we've got in the group and I thought he was brilliant when he came on the other night.
"He was a real threat and possibly changed things in our favour, especially going forward because he looked really sharp. But, unfortunately, with the sending-off it came to an end. Hopefully he can take confidence from that, kick on and start doing it on a more consistent basis."
