We need to get to that point at some stage though. We can't sell our best players every summer and expect to kick on. At some point, maybe not now, we have to break this cycle or we will be condemned to mediocrity in perpetuity.
We aren't selling our best players though. We're selling players who can be sold for far more than their value to the team. The last time we truly shipped out one of our best players was 5 years ago with Arteta.
