This was Mourinho's seventh attempt to steer a team to victory on Tyneside and the United manager was destined for more misery at St James' Park thanks, Ritchie's second-half goal.
The Red Devils suffered a second away defeat in a row in the Premier League thanks to a 65th-minute strike from Matt Ritchie, which extended Mourinho's miserable run at St James' Park to seven league games without a win.
'They fought for their point, a point is what they had in mind'.
"Newcastle played with their lives and defended with their lives".

Paul Pogba was surprisingly dropped against Huddersfield last week.

Paul tasered a dead rat in one of his first posts back (5 minutes in) on February 5-a video that did feature ads . Paul eventually issued an apology on Twitter and later issued a video apology for the incident.
Victory was a huge relief for Newcastle United's manager Rafa Benitez against a man with whom he has often clashed.
The Scotland worldwide struck 65 minutes into a pulsating contest at St James' Park to end the Magpies' wait for a league win at home at the ninth time of asking.
At the other end of the pitch, debutant Martin Dubravka quickly settled into the game.
And United should have equalised soon after, but when Newcastle failed to clear a corner, Anthony Martial saw two shots blocked on the line by Gayle.
United might have gone in behind if referee Craig Pawson had not rejected justifiable penalty claims when Gayle went down under a clumsy challenge from Smalling in the 40th minute.
Lukaku, like the majority of his teammates, had been anonymous. "Alexis (Sanchez) had an open goal and then the countless opportunities of the last 20-25 minutes", he said. But Mourinho clearly felt that Juan Mata and Michael Carrick would be able to unlock the stern door being slammed shut regularly by the Newcastle defence more than Pogba and Jesse Lingard.
