1. They finished 2nd- their highest finish in 10 years. And everyone knows it was a freak season. Leicester winning the title was enough ground for every manger to be sacked including Wenger, Pochettino etc.
They finished on 71 points in a season in which leicester finished on 81. Freak season? Sure. Doesn't make it any less of the colossal, pathetic failure that it was. Pochettino had a tottenham side with an average age of like 10 y/o, and again, tottenham, who finished on 64 points the year before. For all that they unraveled in the final 4 games(2 points) they were very much in it well into april and did better than the previous season. He was the only guy you could forgive for not winning the league. Everybody else rightfully sacked their managers. Except arsenal. For arsenal, doing worse than they did the previous season, bowing out of the title race by march, and finishing 10 pointa behind leicester, while doing feck all in the cups...wasn't a failure, apparently.
2. Conte was basically confirmed as Chelsea manager by early April, possibly the talks had been finalised by mid March- a time when Arsenal were firmly in the title race.
You get in contact with him earlier obviously, and ask him to wait another month before agreeing to take over chelsea. Wenger is on a bigger contract than Conte, and arsenal had CL footie to offer. By April, arsenal knew their season was done. By early April they should have made the decision to sack wenger and hire someone else
Sarri and Jardim extended their contracts last year I think.
It's napoli and monaco. Arsenal can afford to pry them away from their clubs
Tuchel and Allegri are decent shouts but the former is hardly being linked to them and the latter may not want to leave a team that is presently at par or better than Arsenal.
There's quite a bit of talk in italy of allegri wanting a new challenge
Its a well known fact Simeone wants to head to Inter after Atletico's tenure. Also, among the players Arsenal have, apart from Kosc, Sanchez and maybe Xhaka, Coq and Giroud, none of the current Arsenal players look like a Simeone player
It's not a given Simeone will go to inter. As for players, arsenal have money and many of their players can be sold if there's a need. Also, Simeone can just take what he's got and reshape it the way he wants. It's not like Simeone signed all the players at Atletico. He worked with what he had
