Arsenal fans got what they asked for with Alexis. I remember the massive outrage when we sold Nasri and then van Persie. The sentiment then was that we should not have sold to a rival under any circumstances. Also fees were so inflated that summer that the Alexis money would have bought you some magic beans (or Lemar for 90m), so I get holding onto him.
I think losing Ramsey on a free is the only really stupid one, especially given how it all transpired.
