Not sure it will be one player in that L8 position to revitalise Arteta's attacking systems. It will help, but I think the obsession with inverted fullbacks has to change and a fear in losing the ball by playing quickly needs to be addressed. I wonder how much mental/physical fatigue these players are carrying over a very few hard seasons that they will be up for another tactical overhaul.
We also have to be forward looking at how our competitors tactics/personnel, both domestically and in Europe, will develop over the next 2-3 seasons. We have seen how Guardiola's City have reached that inflection point where tweaks to their old style are not as effective any more at the highest level.
I also wonder whether
While we have been very lucky to get two unreal talents break through from our academy into the first team squad this year, we look to be pretty sparse on talent between 18-21 in most positions. I think our transfer budget this summer has to be spent on bringing in prospective talent (like but not to same extent as Chelsea) knowing that hit rate will be patchy. Costs for this will be cheap either, but feel it is something we can't neglect.
I fear next season will be as difficult, if not more so, than this season. Dare I say it, it might be easier to part ways with Arteta in the summer as that might be the best (easier and cheaper) way to reinvigorate the existing squad than relying on several key new signings alongside current players regaining form under same manager.
