Eddie Howe is missing 13 players, some of whom are injured and some of whom are suspended, so I think it's very reasonable that Chesela will take advantage of their weaknesses to secure full points. You could say Newcastle was just lucky because they played in front of their own supporters, otherwise their situation was very complicated.
Knowing all this, Mauricio Pochettino will not miss the chance to earn a couple more points for the team. Most likely, Chelsea will press with attacks. Such a chance does not come along often without taking advantage of it.
Newcastle recently is on a very bad bad form having lost 3 consecutive matches in all tournaments but I think this International break has been of some sort of benefit for them as they have had enough time to fix things even with missing players.The fact that they play in front of their fans is another fact which play in advantage of Newcastle where their best performances have usually happened in this field.
Chelsea is on a great run their own but I think this will be a very difficult game for both teams and I don't know about any result,any result is acceptable in such games.
