Do you mean "our" plan B or "any" plan B?
Danilo seems to have not been thoroughly researched the way the club normally does, just a player who impressed Pep years ago, was on the market and who Pep made a decision to go for after Alves - which seems to disprove your assertion that there's always a plan B - if you believe Sam Lee, that is,and I think Blackburn said the same.
As for Sanchez, I said I think there will a back up, the upper management won't leave Pep without his goalscorer (i.e. there'll be a plan B) and you seem to have taken the opportunity to insult me whilst agreeing with me - are you ok?
