he's certainly going to be able to wheel and deal better than his rivals. But he's starting with a team that is demoralised, and don't know each other. if it was true that PL teams have this massive advantage, they'd come back up every year, and they don't.But are refuting that he spent £150m which he did. As in his time there were £150m of incoming players.
And most championship players are probably not even worth £10m, so for him to sell two players for £60m and be allowed to reinvest that going into the championship, gives him a huge headstart over the rest of the championship. As he could buy 6 players worth more than most teams best player is worth.
