That's a simplistic view of things. Players brought in, performances in certain games, etc...
I'm ecstatic that we are on the verge of winning back to back titles, but now comes the hard part. Staying at the top for the foreseeable future, and making more of an impact in the CL (I was disappointed with our performances in both games against Bayern; I felt we could've done more, even if ultimately we would've been eliminated).
