New Sunderland manager Sam Allardyce has told The Sun that he knew West Ham were talking to managers behind his back - including David Moyes.
So far, Bilic has impressed with West Ham, beating Arsenal, Liverpool and Manchester City away from home, whilst Allardyce made his return to management on Friday, taking over at Sunderland.
Whilst he has arrived at Sunderland and is focused on keeping the Black Cats in the Premier League, it seems that leaving Upton Park is still something of a sore spot for 'Big Sam'.
Speaking to The Sun, Allardyce claims that he knew West Ham were speaking to other managers in a bid to replace him, and specifically named David Moyes as a manager that the Hammers were trying to lure to Upton Park before Bilic's arrival.
"I’d already decided that was going to be my last season at West Ham," said Allardyce. "I knew David Moyes had been contacted about taking my job and there were probably several others," he added.
Moyes, 52, may be managing in Spain with Real Sociedad, but he will now always be remembered for his torrid nine month spell in charge of Manchester United, where replacing Sir Alex Ferguson proved to be a huge mistake for all parties.
The former Everton boss is a proven, stable Premier League manager, but he is also having some struggles in Spain with Sociedad - and West Ham may have actually ended up with a better manager in Bilic.
