I’m not saying he isn’t a successful manager but he has never managed a club in any league that weren’t already highly successful like Porto, or without spending more than his rivals, or were winning the League without him before he took over, and they still continue to do so.
As for winning the CL, he did win it, but with an extraordinary amount of luck as well.
He also only played Monaco in the final.
At Chelsea he bought seven or eight world class players to go with the few world class ones that were already there, and still played a defensive style.
In his career I can’t think of any young players he has brought through from the youth system, and he only buys titles rather than building a team like Wenger did.
This is one of the main reasons he hates him.
He knows that Wenger could have done what he did with ridiculous amounts of money, but he also knows he could never have done what Wenger did by building a successful team with limited spending.
He is also jealous that Wenger was renowned throughout Europe for having the most entertaining sides, but his own reputation is winning trophies playing boring, if effective football.
