Johnson is emblematic of the issues we face whenever trying to strengthen the side by buying big 'proven' EPL top flight players, rather than by developing unproven players from lower leagues, the academy, or aboard.
Previous examples of big money buys who were either supposed to take us to the 'next level' or at least provide a quality-for-quality replacement for an outgoing star man include Benteke, Sakho, Cabeye, Nketiah, Andersen, and Townsend. How many of them get in your all-time XI? Or even your best XI from the last ten years?
1. Any such player is almost bound to be too expensive, in terms of the actual sum and also value. The 'next level' looks like where we are now, a cup win and a lesser European competition. Neither brings in very much money, at least not compared to the cost of tyring to build a 'next level' side. If buying these players is to get us to that level, then the numbers simply do not add up.
2. Any such player is very often stepping down to Palace from a bigger club. I always thought a lot of the players listed above seemed demotivated by a move that probably signals the end of their personal rise. I'm sure they are all very professional, but that's not the same as being hungry. Human beings are what they are, whatever you pay them.
3. Often they can't be sold on for even the same fee we paid, let alone for a profit. Not only are we stuck with them if they underperform, we have often spent so much that we have very little left to play with in seeking an alternative player for their position. Usually buying 'proven' means less of a gamble. In this context, though, its a huge risk for us.
Turning to Johnson, not only has he not scored, he has been very poor in general play, in that he has been completely anonymous. If he was a kid from the youth team or a lower-league prospect, he would have been jettisoned to the reserves months ago, with the verdict that it was plainly all too much for him.
It's getting harder and harder to see that there might be a good player in there. If he gets a run in a different position and system next season, perhaps we will get something back from him, but it would increasingly be a big old surprise.
I've said it a few times now so I'm sorry for repeating myself, but to my mind the new managers first task, and the thing he should be grilled on at interview, is how he plans to get value out of the players we have spent big on, because we are very much stuck with them.
