Although the authorities in his native Thailand continue to pursue him over various fraud allegations, Shinawatra could hardly have a better start to life as a Premier League boss.
"When I first started to discuss buying Manchester City we hoped to be in the top 10 but now I think we can get into the UEFA Cup," Shinawatra told ESPN.
"We are a sleeping giant. I am glad to be the one to wake that giant."
Having already provided Eriksson with £40million for new players, Shinawatra is promising the former England manager more funds when the transfer window opens in January.
And, should Eriksson get the men he wants, life at the Blue Camp will be looking very rosy indeed.
"I thought we would bring success to this club but I did not expect it to be this quick." said Shinawatra.
