If we can do it like Bayern, make an agreement with Pep that he will join us in the summer, then yes. I like LvG's work and I don't have anything against him, but similiar to Bayern with Heynckes we need to think about the club first and van Gaal won't be here long-term anyway. Does it make sense to continue only for a year and to miss out the chance on Pep, who would be the perfect candidate after him and can give us a few years more? Van Gaal already said anyway that he is looking forward to retire and enjoy life with his wife, so maybe we don't even have to sack him, make an agreement with him that he will get money for his remaining year, can retire one year earlier and we are going with Pep. If we don't go for him then van Gaal will retire that year after anyway and we could be in a position where we don't find a proper replacement if Pep joins City and Ancelotti got a new job too. Bayern did the right thing, it was maybe not 100% fair for Jupp the way he need to make place, but Bayern made the right decision for the club long-term.
That said, it seems like Pep will stay at Bayern for 1,2 seasons more anyway, which could be good for us hopefully. I don't think he will be available this summer, but if then we need to act imo.
