Haaland and Salah are both at 14 goals.
Momo will skip games during this month for the African cup, for this reason it will be even easier for Haaland winning the goal leaderboard this season.
Salah and Haaland are lagging behind in terms of goals scored, and Salah has a better chance of winning it because he is currently in form and has a greater opportunity than Haaland. When you consider the entire scenario, Salah is leading Liverpool, and his absence for the African Cup will definitely have an impact on the team.
I agree with you that Salah's absence in the EPL will give Haaland an advantage to top the highest goal scorer this season and let's look at it this way, Haaland hasn't been in action for a while and we don't really know when he'd be joining the team but I don't think he can come back and start scoring goals from where he left it. He might be rusty in the game and it will take him like 4-5 games before getting those scoring ability back.
While the City striker is trying to recover I feel Dominic Ayodele Solanke would try to get past Haaland and Salah that's if Bournemouth continue getting things right and the striker (Dominic Ayodele Solanke) continues scoring goals. I just have that feeling that he can get more goals than Mo Salah and Haaland.
That is even better, and in addition to Haaland's advantage, Manchester City will benefit as well, as it appears that Momo and Salah won't be available. The defending champions, Manchester City, will undoubtedly prevail no matter what the obstacle, and I also have a strong feeling that we will win the Champions League. Furthermore, Haaland will continue to be the line with the greatest goal total.
And Haaland not been in action was as a result of the absence of De Bruyne absence and am so happy that my man is back. And you will see that our mood of playing will change. Once he plays one or two game everything will be in place again I trust Haaland.
