And when Mane or Salah gets injured we've got... Ben Woodburn and Ryan Kent.
This is somewhat true, but it's more down to Barca's wage allocation than fees. They have a lot of ageing players on ridiculous salaries, and they simply can't afford to offer decent wage packets anymore until the likes of Messi and Iniesta move on, whenever that may be. This is why someone like Umtiti is unfathomably only on 40k per week. Obviously they've got some wiggle room now what with Neymar leaving but Dembele and Coutinho together would most likely be too much.
