The 25-year-old ace looked to be heading out of Anfield after being courted by Barcelona over the summer and handing in a formal transfer request.
However, Klopp and Liverpool were adamant that they weren’t selling him and were true to their word, despite reported offers of over £100m coming in for the player.
Fans aren’t willing to completely forgive straight away though, with one saying he had a lot of grovelling to do – and that he could make it up with goals.
Others warned fans inside the ground not to boo as it could have a negative impact on the team’s performance.
The overriding message was supportive, although lots of fans are wondering what sort of reception he’ll get if he’s introduced into the action.
This Is Futbol has rounded up some of the best tweets from Liverpool fans ahead of the 7.45pm kick-off.
Coutinho has a lot of grovelling to do. In the form of goals, of course. pic.twitter.com/TRs1qRfHpP

I can see coutinho coming off the bench & scoring. As long as he doesn't kiss the badge celebrating ????

Be interesting to see what kind of reception Coutinho gets tonight when he comes on, Sanchez received a mixed one at Arsenal on Saturday.

Coutinho needs to be greeted with the roar of anfield. He doesn't deserve it but that will teach him more of a lesson than booing him. #LFC

Use your brains if youre at the game tonight people. Don't boo Coutinho when he comes on. All it will do is potentially effect performance

Keeping aside my bitterness about Coutinho,it's about time we saw the little Brazilian magician play #LFC

Cant believe we seriously rejected 130M from Barca for Coutinho and spent 30M on Oxlade Chamberlain to not start either of them in the CL
