Sunderland's preparations for the coming Championship season were dealt a blow on Thursday as Derek McInnes opted to stay at Aberdeen rather than take up the manager's job at the Stadium of Light.
The Black Cats remain without a first team boss with the new season moving ever closer and nerves are understandably jangling on Wearside.
But Sunderland must remain patient in their hunt for a new manager as past results show teams have struggled in this division after making the wrong pre-season choices.
In the last two Championship seasons, the three sides to bounce back up from Premier League relegation have all seen their coaches see out the entire promotion campaign.
Sean Dyche's Burnley won the title, so too did Rafa Benitez's Newcastle United, while Steve Bruce and Hull City progressed through the play-offs.
By contrast, Queens Park Rangers, Aston Villa and Norwich City all changed managers during the season - after a bad start - and failed to recover and mount a promotion push.
While Dyche, Benitez and Bruce benefitted from additional time to work with their players, they were also clearly the right men for their roles and capable of the job at hand.
If Sunderland rush this decision, after the disappointment of missing out on McInnes, and appoint a Roberto Di Matteo - like Villa did - this season could be a slog, even if they correct the error with a second managerial change midway through the campaign.
