The 24-year-old Egyptian international has already agreed personal terms with the Reds and just needs to have a medical before the transfer is completed on Wednesday.
If the transfer goes ahead he will become the club's most-expensive signing, eclipsing the £35m forked out for Andy Carroll six years ago.
Salah has already requested the number 9 shirt, previously left vacant since Christian Benteke's departure for Crystal Palace last year.
