You talk about age and stuff but how does this matter when Alsonso won the league in his first season, without a loss, and Arteta needed 3 summer windows before we started looking like a football club again? It doesn't matter at all, Ange in his first season showed brilliant football and you could even argue they almost played the best team in the world off the park. I'm pretty sure next season they'll compete for the title(Liverpool's spot), he looks 100x better than that fraud at United.Nothing because again, he's done nothing in a proper league and he's already almost 60. He's got like 6-7 years left in his career and hasn't shown anything at the top level. Football has more managerial turnover in the modern era than it ever has. If this man was a top manager, he would not have made it to 58 with the SPL as his biggest job. If you show any kind of elite managerial potential, clubs are bending over backwards trying to hire you in your 30's or 40s. This is why Nagelsmann, Xabi Alonso, Xavi, Arteta, Amorim etc. have all been hired or pursued by at minimum PL standard clubs if not truly elite ones by their early 40s.
He wasn't even Tottenham's first choice, they were turned down by numerous other managers with experience in proper leagues. Where is he getting the money from by the way? Levy is as tight as it gets and they've now got a 2nd season of no CL football because his Captain missed a sitter, possibly on purpose. No sir, he made his first tactical change in the 37th match of the season and now they are in no position to attract proper player because they have no CL football and no player worth their salt is going to sign up to play for a club whose fans are Arsenal voyeurs before they're Tottenham supporters.
