On paper I'm sure Arsenal will still have a chance to win, moreover Arsenal will play at home because so far this season Arsenal have always won when playing at home. Also, after this World Cup, the fact is that Arsenal can still play well with the two wins they got in the previous two matches.
So yes, Arsenal are still the favorites anyway as they will certainly make a big effort to maintain their good record so far.
But even so, even though Newcastle in the previous match was held to a draw by Leeds which of course is an unpredictable result too. So it seems that at this moment I have to get out of the way or have to get out of the predictions on paper. Because I think Newcastle could have made a surprise in this match by holding to a draw or maybe beating Arsenal.
If Newcastle manages to hold on to a draw or beat Arsenal in this match, then Newcastle can stop Arsenal's winning record for their home matches this season.
