We cannot really tell what the outcome of the match between Chelsea and Newcastle will turn out to be because in as much as Chelsea seem to have been in a good form do to there wining against Tottenham Hotspur and drawing there match against Manchester City doesn't prove that they can easily win Newcastle United because Newcastle also have so many good records this season even if they were unable to have gone far on this season premier league but to me they have the same form and performance as Chelsea so there upcoming match is actually going to be a 50 to 50 in performance so at the end we will know who is the strongest.
Basically, the chance to win for both teams will be always 50:50. I agree that both Chelsea and Newcastle players have almost the same quality. Also, the stats of their last 5 matches seem not very much different. But what makes them are different, it is related to the condition of their attackers. If you look at closely, almost all Newcastle attackers get injured. They even have no available striker for the match against Chelsea. I think it will be a big problem, they can't optimize their attacking line. That probably makes Newcastle to play more defensively. This is surely an opened chance for Chelsea to win the match. So, I personally predict that Chelsea will win the match.
