Allardyce, a friend of the United boss, was sacked by Rovers earlier in the week by new owners Venky's, despite bringing stability to Ewood Park in recent years. Ferguson blames the involvement of player agency the SEM Group and sports rights agency Kentaro in advising the new owners at Blackburn for Allardyce's sacking. Indeed, the Premier League is monitoring the situation at Rovers, concerned there may be 'undue influence' on the way the club is run. Ferguson believes the changing nature of the game means it is difficult to create stability and a long-term plan. "I think it's very difficult these days (to build a club) with the life we're in now," he said in the Sunday Telegraph. "There's intense pressure on managers. "You've got that issue at Blackburn of an agent involved and deciding the future of the club, Jerome Anderson (of the SEM Group), he couldn't pick his nose. "It's baffling and it's a serious threat to how clubs get run and how they conduct themselves. "It's becoming trendy to sack a manager in difficult circumstances and I just wonder whether Blackburn thought, 'You know, if Newcastle can do it, we can do it'. "I don't know the answers to it, but what I can say is that a manager's job, whatever he's getting paid, it's not worth it. If Sam had won on Sunday, they'd have gone fifth in the league. "But he still would have got sacked because they would have said they should be fourth." Ferguson became United's longest-serving manager on Sunday, breaking Sir Matt Busby's club record. Blackburn, meanwhile, have not found a replacement for Allardyce and the search for their new boss continues.
