Did you say easily? I doubt that it will be easy for Manchester City to get all three points that day. My reason is because almost all the teams in the EPL have increased in their performance and Newcastle is not exempted. Aside from that, we have seen Newcastle to be a challenging opponent to Manchester City in the past season. There was a time when they won Manchester City even when they were still in the best performance.
Even as Manchester City are facing some injury problems currently, some of their players won’t be playing some matches, so there is a slight decline in Manchester City's performance, but even with their current performance, Newcastle shouldn't be so difficult for Manchester City to win. I am expecting three points from Manchester City in the match, even if they won't be able to score so many goals in the match, but Manchester City can't afford to drop from their current first position, and if they can lose against Newcastle, then another club will take the position from them, so Manchester City won’t want to lose to a club like Newcastle.
