The Reds moved up to the top of the table with six games left to play thanks to a comprehensive 4-0 win over Tottenham at Anfield on Sunday.
With Chelsea and Manchester City still due to travel to Anfield before the season is out, Liverpool’s fate is in their own hands.
And defender Johnson believes that the Reds have already proved themselves as genuine contenders.
“Any team who is top of the league at this stage deserves to be there,” Johnson told the Liverpool Echo.
“This is a difficult league with a lot of tough games but I think we can stay there.
“This is a fantastic club. Everyone involved here loves it and wants to win the league badly. We want to get the club back where it should be.
“Playing in the best league in the world, the hardest thing is to go game by game.
“Every day you’ve got your mates texting you and you see on the news how close you are. But everyone here is professional. Every time we come here we have a job to do.
“We just need to think about West Ham away next Sunday now and concentrate on that.”
