"You might be going in what you think is the right direction but if it's not the place the owner wants, then you're in trouble.
"I'm sure the Chelsea fans have enjoyed the last three seasons.
"They hadn't won the league for 50 years before Jose took over. Even last season they reached the Champions League semis, won both domestic cups and finished second.
"But if the person in charge wants something extra, you're not managing the situation properly."
