no, you won't sell your entire front three at once (i never suggested that) i merely said that your current model that you've built your house on has been to capitalize on assets before they have started to decrease. and as such agewise sadio, salah and bobby are getting to be up there, and that one of them is likely to get sold next year. and this goes back longer than klopp, suarez (you got 65 mill pound for him, in 2014 that's alot for a 27 year old) comes to mind.
personally i would sell salah for an outrageous amount to one of the spanish clubs (or psg) and then buy sancho from bvb.
