I think the game is open to be won by either of Chelsea and Newcastle United. While Chelsea are knownn to be an inconsistent team and poor in front of goal; this season Newcastle United has also been inconsistent and injury ravaged which is enough reason to help gamblers understand its either any team wins or a draw ensues
Personally, i think Chelsea will win the tie, they are in good spirits and better form as well.
A trip that might be quite good for Chelsea if they can win the match against Newcastle United because this match is an away match and Chelsea previously managed to hold off Manchester City and also beat Tottenham. So if Chelsea manages to get 3 points at home to Newcastle United then Pochettino will be highly praised by Chelsea fans because he has succeeded in bringing about significant changes in the several matches they have played. I see that Chelsea is quite superior in this match, especially since they have good enough capital to face Newcastle United.
So, if Chelsea manages to get 3 points, I think they will be closer to the top 4, therefore Chelsea cannot afford to lose points in this match. Newcastle United is experiencing a downward trend this season where in their previous match they were defeated by Bournemouth and in the match against Chelsea I think they will find it difficult to recover from their defeat. So for this match I think Chelsea can take advantage of Newcastle United weakness because if Chelsea can score early they will be superior enough to secure 3 points.
