Blackburn Rovers' global advisor Shebby Singh has warned the incoming boss at Ewood Park that they must deliver immediate results.
"The new manager must understand he will not have two or three seasons to build the club - he will be under pressure straight away," Singh told the Daily Mail.
"If he doesn't get it right we will have a chat about things. He doesn't have to worry about losing three games in a row at the start - because he's new we will give him a few more."
While making it clear that there is an expectation to succeed at Ewood Park, Singh insists he will not interfere in team affairs once a managerial appointment is made.
He added: "We don't want anyone to be frightened or worried about coming here. The objective is to build a team but it's not like going to a supermarket and picking a manager off the shelf.
"They don't have to worry, I'm not going to be the manager, I wouldn't insult other managers or coaches. I am in a supportive role. I'm not here to breathe down the new manager's neck, I'll be his biggest supporter."
