From my understanding of Pep's personality, he will never leave City when we are doing poorly. But, Pep may not like the idea of Messi joining city. From the day Messi option started, Pep's attitude changed. Pep wants to win things with us, but he does not want Messi to take the credit for it. Unfortunately, for obvious marketing reasons, we need Messi :( But, if I have to chose between Pep and Messi, it's always Pep. I will be more than happy to finish within top 4 and call it a success.
Reading the posts, I honestly feel happy that fans are not in charge of decession making at the top. It needs to be logical, most fans are way too emotional for logical thinking.
