Good points.
However in our defense, the final League placing is a bit of a " False equivalency " due to Manager change, performances and disruptions ( Losing our best player, management and coaching changes, injuries etc. ( Since he who I know better than to name on this site, lol , has been in charge, we are/were 9th in the form table, and have actually been unlucky with alot of results. We're a couple of players short of being a very good side, we've had some glaring holes for a few seasons which have not been addressed, until now. IMO ( Yes i know, it's not a great deal better and has nothing to do with the ACTUAL League placing )
I'll be honest about the reasons why players make " sideways " moves. Firstly, as you probably know, agents play a massive part, then silly money, the " The Project ". The likes of Kamara, Coutinho, Carlos all could have gone to CL clubs.
The other part is down to Richarlison himself, he might want to leave for a CL club, but will the interested CL club want to pay the fee and wages he would want? ( Will the " sideways club " ? )
Your board and Manager obviously too, play a part, what if after a poor season by your standards, they've simply decided they want to cash in on elements of your team for a rebuild, and will sell to whoever matches their evaluation?
For all you know, you could have better players than Richarlison lined up to sign yourself, for half the money.
The reasons why we will undoubtedly start to see Newcastle pluck players they " Have no right to be signing " from all over the place. It ain't because they are a CL club is it?
