Don't get why people are twitchy myself. Pep said himself that he feels Erling will always be motivated - pretty sure this is never going to be a Mudryk or Bogarde situation! And touch wood he's been ok with injuries.
One other thing - this could help dictate our next manager. Pep is likely gone in 2 years, Erling and Phil will be around 27 years old and at or near the peak of their powers. Who knows we might not see the best of Erling until Pep goes. Knowing we've got Erling tied down should be a big help with any transition and plans moving forward
