short term is fine, lets see what happens when they move stadium and compete in Europe eh. Dont splurge too early now
Which has what to do with what. Circumstances change, jobs get harder, even with the stadium move Spurs will have a large budget disparity to us. Last year we spent 195mil, they spent 100mil... and City spent 198mil on wages. In general if they want to become a 200mil a year team they'll need consistent CL appearances and a 50mil boost from stadium income. The latter is doable but likely won't happen. They could have been charging the same ticket prices as we do but at their current stadium. They'll likely gain between 35-45mil revenue from the next stadium which will certainly help bridge the gap somewhat. but they'll be in a 'growth' phase, I'd expect some issues adjusting to compete in multiple competitions. But ultimately if you're buying players then improving 90% of them on what is a solid base of a team you can't go too far wrong.
But again, what does that have to do with it. Wenger is doing worse today than he was in 2004, much, much, much worse despite a much much bigger budget compared to back then. How on earth can we have a nearly identical wage bill to City.... when we have Giroud and they have Aguero, when we have Walcott and they have De Bruyne, etc, etc.
What matters is the basics, is your manager improving the players in the team through training... yes, manager is doing a good job, no, manager is doing a poor job. Are your tactics working, yes, good job, no poor job. Are your players well motivated, are your players able to cope with the pressure of big games, etc, etc, you get the picture. As above, the basics of management, improving players, tactics working, motivation and mental strength, if these things are all MASSIVE problems, it has nothing to do with finances, it has nothing to do with how many games you play or in which competition. These are basic things that make a manager good or bad. From 97-2005, just about every player improved while at Arsenal, we had the mental strength to compete in all competitions, we won league titles, our tactics were solid and all players seemed motivated. Both with the first team doing exceptionally in the league and don't forget, our youth team(by and large) able to take on the league cup to the late stages and actually play some genuinely great games with great performances. The whole club was different back then.
Then something else to think about, the only real success Arsenal have had under Wenger, was with a 4-4-2 that was mostly based around an all out attack but was insane on the counter attack. The current slower possession based Arsenal who score far less on the counter is a completely different style. This style/tactic, which we've been using since 2006 at the latest... has never had us win the league, has never seen us do well in europe, Wenger has had next to no success with it. We played very different and hugely more effective football while Wenger was genuinely successful. Based on other things, mental success, defensive solidity, ability to see out tight game by going defensive, ability to do great in the big games and ability to win league.... I think other people at the club were crucial.
He inherited a solid defence and monumental leadership, we had other coaches, other scouts, and different players at the time. I think probably a large portion of what made us great was the particular combination that was had at the club, mentality/strength coming from Adams, Keown, Winterburn, Dixon, guys who trained with them daily would have Adams on the pitch telling them what they were doing right, what was wrong, where to stand, when to cover, this makes a huge difference.
There is both something clearly missing that was with us from 97-04/05 and isn't there now but most importantly it's something Wenger has had over a decade to find and fix and has failed to completely.
The basic starting point you want from a manager is, improve the players you have, improve the players you bring in. Not every season will be great, not every buy will be great and not every player can be improved.... but you need to be showing improvement overall. Luck will be with you one year and not another, if every year is bad, no one is improving and overall nothing is improving at the club... management needs to change.
