The Chilean has added energy and drive to Mourinho's side, and that will be needed against a Newcastle team battling relegation. Newcastle needed an inspiring performance to defeat Manchester United, especially after their run of form at home (no wins since October).
Pogba played nonetheless but he clearly didn't look anywhere his best, ambling through the game and hardly ever producing a decisive touch, and was hooked off for Michael Carrick soon after his failure to compete at a set-piece allowed Newcastle to score. Truly an electric atmosphere.
Man Utd have kept a clean sheet in 5 of their last 6 matches (Premier League). One goal behind Tottenham's Harry Kane, Salah could yet head to his first World Cup with Egypt as the Premier League's top scorer.
Joselu could return for the home side after the Spanish striker missed the trip to Selhurst Park through illness, while Slovakian goalkeeper Martin Dubravka and on-loan Leicester forward Islam Slimani could make their debuts after arriving at the club on transfer deadline day last month.
The second half was wildly entertaining as every player and fan knew what was on the line.
Ritchie's goal came from a free-kick awarded for a needless dive by United defender Chris Smalling inside his own half.
Ritchie's victor came from a clever flick by Dwight Gayle after Jonjo Shelvey's lofted free-kick had been headed down in the area. Ritchie slammed the ball to the left of De Gea, low enough where a save would have been near impossible.
United's profligacy was punished when Ritchie pounced for his first goal of the season, sparking delirium in the stands.
For a man that has enjoyed plenty of success on English soil, including winning three titles, it is somewhat surprising that the Portuguese has failed to win in his six top-flight visits to St James' Park. "I never had one single problem with him regarding his professionalism because he really is a very good trainer, one of the guys who likes to train, enjoys to train".
"We were doing well for a while (going forward), then we were defending, but the teamwork and the way they fought for every ball...was fantastic". They are only 3 points away from Bournemouth who are in 10th place.
"Still we were a little bit lucky at the end, but I think the team deserved three points in any of these games and if it's this one, even better".
