This match is really hard to predict... Chelsea still hasn't completely won me over, even though their performance is gradually getting better. The return of some players from injury might be the key to the top-notch performance Chelsea could display.
If the performance shown against Manchester City can be maintained, then there is a big chance that Chelsea can beat Newcastle in the match played at St James Park. Moreover, several players have returned from injury so there is no reason for Mauricio Pochettino not to be able to beat Newcastle if Chelsea wants to move up to the top 4 of the Premier League standings.
