Sorry, but no-one with any sense would sack their manager based on results after just 3 league games (one of which we won 4-0!)
If Cortese was unhappy with Pardew at the end of last season (which he had no reason to be based on performance), he should have had the bottle to get rid of him then.
Having to get a new manager in now, at the end of the window, is the worst of all worlds IMO.
