I read an interesting article a few backs that expressed the opinion this will become the new norm. Clubs will allow players honour their contracts and leave for free. The days of being stuck with an Ozil or Bale are a thing of the past. It's fair point too, some players age gracefully, others just hit a wall one day and they're done.Saw slbsn (@projectriver on here) mention this on Twitter the other day, but potentially a bigger problem for Liverpool is the fact that Salah, Mane and Firmino are all 29 and also entering the final two years of their existing deals. They'll be reluctant to offer them all lucrative new deals, but replacing them were they to run down their contracts would be incredibly expensive.
