We should not rely on Kompany at all. His so injury prone and after a long period of no games and finds his way in the starting XI, he will be making mistakes. I feel for him, his such a quality CB but we better see a CB come in on January. Pep knows this season is a great chance to win the title and shut the critics up, no telling how things are going to be next season, so now we really have to throw everything we got at it. In order to continue to win, we have to get someone else. Pep doesn't trust Mangala, and even stated he won't stop him if he wanted to leave, I mean that is him just saying, "Mangala, I love you but gtfo!".
In terms of options.
I would love to see VVD at City. Idk about you guys but I've always seen him as a younger version of Kompany but with speed and much better on the ball. The problem will be that the Saints will demand so much money. Imo, I think he will go to Liverpool because VVD was already pushing to go to the club before the window closed. Liverpool want a CB badly and will wait until the summer. I doubt he joins us. I mean for Liverpool the price was 70mil, what do you guys think the price will be for City, 90mil? I just don't see Pep wanting the club to break the bank for him. I think either Ingio Martiniez or Johnny Evans will come in.
