So that is what is happening this season? No?
Wenger has signed players, has improved the squad, has tried to improve and their form (according to yourself) is only 5 points behind last season.
Wenger clearly tries to improve the football, squad and first team season upon season
.
He has failed to address any of the reasons we lose such games repeatedly, buying a new player is meaningless if you give Walcott a new contract, bench your most in form players because Walcott/Ox get fit again(Campbell is 5 times the player of Walcott or Ox yet was instantly benched again when they were fit). He makes woeful substitutions, the mentality of the squad is wrong, he buys the wrong types of players.
Presuming that buying one player will have a dramatic effect on the squad when that isn't amongst any of the biggest reasons we suck is just dumb.
We've been buying new players every season for the past decade, mentality, tactics, wenger's sub choices, Wenger having favourites who get played no matter how bad they are. Sanchez being in shockingly bad form but not being dropped, buying someone as poor as Welbeck as back up to Giroud rather than buying a top striker because Giroud isn't good enough.
Wenger had 200mil sitting in the bank, at least 100mil + that could be spent and refused to buy a DM which meant we lost loads of points when Coquelin couldn't play because Arteta and Flamini are no where near good enough.
Buying one player, who wasn't the biggest issue, and losing all the points we have for all the long term issues he has failed to address in the past decade isn't 'improving'. The team hasn't improved, they play exactly the same football, they fail in exactly the same way, they fail to turn up to exactly the same games, they still have a mentality problem.
Also we are 5 points worse off, not sure why you think that is decent, it's 10 behind the same point in 13/14, the last time we won the title we were 21 points better off after 29 games.
21 points worse off than the last time we won the title where in between our budget has tripled... is improving?
