The Magpies head into the Saturday lunchtime fixture with the Hammers six points above the Premier League relegation zone, and 23 below their visitors.
Moyes’ side have been one of the success stories of the season by competing for a Champions League spot, whereas United’s campaign descended into chaos following a recent run of two wins in 20 matches.
Despite the side’s contrasting fortunes, Moyes believes Bruce has done a good job at St James’s Park. He also backed Mike Ashley’s decision to stick by the 60-year-old when fans have demanded he is sacked.
Moyes said: “I think Steve has done a good job, he has done what he has been asked.
"I have to say, I think he has had really good support from his owner in difficult times and I think because of that you will probably see Newcastle stay in the Premier League when many people thought there should be changes.
"The owner gets criticised a lot for the decisions but maybe the owner has made the right decision.”
Michael Owen tips Newcastle to draw with West Ham
Former Newcastle United flop Michael Owen has predicted his former club to hold West Ham to a draw this weekend.
Owen feels Bruce and co are closing in on retaining their top-flight status and believes another point in the right decision will come against the Hammers.
A win for the Magpies tomorrow will see them stretch their lead over the bottom three to nine points before Fulham take on Arsenal on Sunday.
"West Ham’s incredible season continued as they won their crucial match against Leicester at the London Stadium," Owen told Bet Victor.
"Their dream of playing Champions League football next season is very much alive, however, first they must overcome a Newcastle side that will feel there is light at the end of the relegation tunnel.
"The Magpies have shown some grit in the last few weeks, and back on home soil, I think they’ll have enough to take another big point."
