While Sunderland supporters will be rightly excited to welcome the experienced Sam Allardyce to Wearside, the West Ham United faithful will have grown tired of the coach moaning about how he was treated at Upton Park.
Indeed, he is quoted as telling the Sun on Sunday recently by Sky Sports: "When I was at West Ham my wife would constantly read the supporters' websites to see what new insults were being fired. It upset her but she couldn't keep away from the screen.
"Now she's been reading the Sunderland fans' sites and she tells me the reaction has been very positive, which makes me very excited to get going.
"It wasn't just me at West Ham, it was every manager that was there. I got it because I was manager at that time but before that they moaned about Avram Grant, Alan Curbishley, Alan Pardew and Harry Redknapp."
Needless to say, this is a man who won three out of his last 20 Premier League games at West Ham. This is a man who, after reaching the 'magic' 40-point mark, simply packed his bags and went for an early holiday. Allardyce needs to stop with all this, man up and take responsibility for doing a shoddy job.
There's also the small matter of Big Sam being fickle, of course. The Sunderland fans certainly love him now but, were he to deliver three wins in just 20 at the Stadium of Light, the 60-year-old would go right back to being public enemy number one.
He would at any club. Doing a terrible job and then moaning about criticism is a sign that you may no longer be cut out for management.
It's almost as if Allardyce feels guilty for just how badly he performed in his last months at Upton Park. Why else would he bother going on about West Ham's fans?
It's unprofessional to say the least and the 60-year-old is already wasting energy discussing the Hammers in newspaper columns rather than focusing solely on Sunderland.
Certainly, as a human being, Allardyce is entitled to hit back at abuse and sing the praises of his new fans. He may also do very well at the Stadium of Light and, deep down, supporters of his old clubs wouldn't begrudge him any success.
But the time for petty jibes is over. Big Sam has had months to spin his own deluded version of reality. By now, the new Sunderland boss has simply become a broken record. And he's fooling no one - least of all West Ham fans.
