The Reds could do with a win in the Premier League as they currently sit 11th on 14 points, but are just four points off a place in the top four - but they will have to do it without Daniel Sturridge, and there is talk that Mario Balotelli may also miss the trip to face Neil Warnock's side.
Following the clash on Sunday is a huge trip to Bulgaria take on Ludogorets in Sofia the Reds need a win to keep their destiny in the Champions League in their own hands.
In an interview with the Liverpool website, Johnson seems primarily focused on the challenge of facing the Eagles on Sunday lunchtime, saying: "We have got to take the weekend first and hopefully get three points and then we can hopefully go on a good run.
"Crystal Palace have obviously had a break as well and will have been concentrating on this game since their last one. They need a few points, so it's going to be an important game.
"This is the Premier League and every team is tough to beat. It's never as easy as it looks on paper. Every team is fighting for their lives or fighting to climb up the table with those extra points."
One thing that could help the Reds come out of this week with positive results is an improvement in form from Johnson, both going forward and defensively.
There have been times when he has been beaten defensively time and again and his lack of composure on the ball can prove costly. At his best he can come up with a good final ball which would help aid a Liverpool side that has been struggling to find their feet in the final third of the field.
Two wins this week for Liverpool could be massive in what is a winnable run of fixtures for the side who need to find some momentum ahead of a difficult December. Find that and their season may become a little brighter.
On a personal level, Johnson has something to prove. Despite reportedly turning down a contract offer from the club where his pay was significantly reduced, the right-back is out of contract in the summer and needs to perform well on a personal level in order to find a new club.
