It seems Salah wants to stay in Liverpool for a long time and this can be good news for Liverpool because of having this player for a longer time.
We recently saw news about Salah leaving Liverpool for the Saudi League because of the better money he could get there and he could end his career in this league but he decided to stay in the Premier League and keep playing for Liverpool. After Liverpool won the game against Manchester United, Salah said they didn't try to expect the contract of him in Liverpool and he was unhappy because of this. Which shows he wanted to stay there even for a longer time.
Mohamed Salah will remain Liverpool's mainstay as long as Liverpool do not bring in new players or its competitors but if the situation does not allow him to be a starter, Salah will consider offers from other clubs, besides that we can see certainty about Salah next season when his contract ends in 2025 well that's a good time to evaluate including salary issues and others, usually when older players will get a pay cut especially if their performance declines.
For this season, Salah can still compete with other top strikers and he is still in the top 2 meaning he still has the ability to be a main choice in the lineup. Throughout September, Liverpool is still safe in the standings because they will face weaker teams but when entering October Liverpool have stronger opponents such as Arsenal, Chelsea and Aston Villa well that's the real challenge if Liverpool can overcome this then they deserve to be considered as a main rival for Manchester City..
