A lot of the talk in the run up to the game was of tactics, systems and how Bruce was seemingly struggling with the hand he was dealt.
Here we take a look at the changes the head coach made on Sunday – and how that contributed to the Magpies’ second win of the season.
Matty Longstaff was a revelation on his Premier League debut, covering more kilometres than any other player on the park. Since the loss of Mo Diame and Ayoze Perez, United have missed that 'hassle factor'.

Allan Saint-Maximin's arrival in the Newcastle team has brought some much-needed pace on the break, and some tricks, to cause defenders problems. The winger might have lacked the end product but he gave Man United nightmares when he broke in the first 45.
United had genuine width against Man United, which meant, with the ball, Newcastle often had their two full-backs and Allan Saint-Maximin and Miguel Almiron joining Joelinton in a front five.
This selection call was a big one - not quite Longstaff proportions, but controversial all the same. Ciaran Clark never lets Newcastle down and he didn't again when coming in for Paul Dummett, who has seen his form dip in recent weeks.
Andy Carroll was brought on in the 56th minute on Sunday and he got half an hour at Leicester. With Joelinton struggling for confidence it would be no shock to see him taken out the team after the international break. Bruce certainly seems to be heading that way.
This was a move back to Rafa Benitez's team and system but it was very different in many ways despite some similarities. This was a much more open, attacking version with real width and full-backs bombing on. And on the day it worked a treat.
The manager convinced everyone he would shut up shop and go back to Rafa Benitez's 5-4-1 against Manchester United but he didn't, he had his players go at the Red Devils from the off.
