Former Newcastle United boss Sam Allardyce fears that his old side will be relegated unless Rafael Benitez and Mike Ashley resolve their disputeThe Magpies are winless and joint bottom of the Premier League table with just two points from eight games.Manager Benitez has grown increasingly frustrated with Newcastle owner Ashley’s lack of support in the transfer market.But Allardyce, who was fired by Ashley in January 2008, believes that Benitez must succeed regardless of the resources at Newcastle.“If you’re going to be successful, harmony at the top’s very important – communication and pulling in the right direction,” said Allardyce told PA Sport, via ITV.“Whether that’s happening with Rafa and Mike, I’m not privy to that information, but certainly, from my point of view as a manager, the relationship between the owners and you as a manager is critical.“(A club) can succeed but you have to put your differences to one side, both the owner and you, as the manager, and work together to get on with the job.Virgil van Dijk praises Roberto Firmino after Liverpool’s win Andrew Smyth – September 14, 2019 Virgil van Dijk hailed team-mate Roberto Firmino after coming off the bench to inspire Liverpool to a 3-1 comeback win against Newcastle United.“Whether you like each other or not doesn’t particularly matter; as long as you do the business and the best for the football club.“I was there for seven months and never really had a relationship with Mike – he wasn’t the type. He wanted other people to run the club and he wanted to come along and enjoy the ride. I don’t know whether that’s changed or not.“Because (in the transfer market Benitez is) limited, as we all find ourselves with whatever club we’re at, we try and use our tactics and the players we’ve got to the best of our ability.“The Newcastle fans give (Ashley) a lot of stick, but he is the owner of the football club and he has put his money in.“Whether that’s enough or not he decides how much money he wants to give the club and it’s up to you as the manager to try and spend that as wisely as you can.“Only time will tell if Rafa has. He certainly did last year; he finished very, very strongly. This year’s a difficult start but maybe again they’ll come through. New players again – we all have to settle players in very quickly, and that’s very demanding as a manager.”Newcastle will next face Brighton in the Premier League on October 20.
