Yea, you say that, but if Ozil leaves and Bayern sign him up, everyone and his dog will be after Wengers head. Ozil isn't the problem, we have issues with big game mentality when going 1 down.
Greizmann would help
Kroenke, get your wallet out!
It's got nothing to do with going one down, and it has got to do with Ozil.
I watched him a LOT for Real, he was the same there, he's the same for Germany. He wasn't spectacular in the world cup for Germany, he was no where near the best player and he was invisible in more than one game. He frequently went awol for 90% of games for Real and often had terrible performances in the toughest games. he can't take pressure, he's a giant girl and pushes the ball away more often than any player I've ever seen if he thinks a big tackle is coming in.
Today while at a bad point of the game in the second half the ball came to him and without looking around at all he just flicked it up direct to a Chelsea player because he thought the Chelsea player was going to come in and smack into him, rather than win the freekick he gave the ball away, I honestly can't think of another player who does that at all let alone as frequently as Ozil does it.
If he goes to Bayern a lot of fans will complain about it, but in reality he'd make Bayern weaker. It also isn't a good argument because Wenger these days constantly antagonises the fans by telling them their opinion doesn't matter, so what would it matter if they complained about letting him go.
Back in the day he pushed Petit and Overmars out to bring in Pires and Lauren, better players who improved the team. He doesn't care about what the fans say and more importantly, back when he was successful with Arsenal and winning titles, competitive in the CL he'd have pushed out Walcott, AOC, Ozil for not being good enough already.
I added your edit, Griezmann wouldn't help, the quality of players, well it is an issue, but isn't the major issue. Griezmann would be another top player who would be let down by the likes of Walcott, Coquelin and whatever it is that causes constant injuries that Arsenal are getting wrong physio/medical/training facilities wise.
As for Kroenke, one, he'll never ever get his wallet out, two, he doesn't need to. He isn't taking significant money out of the club(a 3mil wage/consultancy fee is nearly meaningless and fairly standard), he leaves it in Arsenal's accounts, Arsenal still have 150+ mil in cash available to spend in the bank, we can spend whenever we want to, Wenger thinks he has the right players, Wenger is wrong.
Look at Spurs, before Poch joined Spurs I was calling on any manager for a few years before that to come in and do what he did for Spurs. He went in, identified all the players with the wrong mentality, who weren't good enough and he got rid of them. The fans loved Sandro(no idea why, never rated him at all), he shoved him out, along with other liked players. He came in without the sentimentality, without having seen a kid come through the ranks or without having spent big money on those players so he had no vested interest. He didn't want a kid to make it or didn't want to be proven wrong because a transfer failed and he just purged who needed purging. Spurs are massively improved for it.
If a manager comes in they'll spend two weeks training with the team before, without sentimentality or wanting to prove a bad buy, purge the team of the same type of players Spurs got rid of and Arsenal will be drastically better for it.
For me Wenger spent 42mil on Ozil and can't admit he's a flop when it comes to big games and was never worth 42mil or a big wage. He wants Ozil to prove he was right rather than cutting his losses and bringing in the next Pires. He wanted to prove Walcott wasn't a mistake at 15mil, same with AOC, over and over. Wenger rather than getting rid of players who he thought he could improve on as with Petit/Overmars, is trying to prove he didn't make mistakes regardless of how clear they were.
