There have been several teams that found it difficult to beat Chelsea as of late. But Newcastle has the home advantage and I think they won't lose this game, but at the same time I would say that Chelsea has developed well and they have shown that they should not be written off too early this season. It will be a close game with many chances on both sides I think. But if I should pick a team to win this game, I would still go with Newcastle as they have had some incredible games in their stadium at home.
It is true. Chelsea became an obstacle for Tottenham and Man City. Chelsea stole points from those teams. So, it makes sense if people assume Chelsea will steal points from Newcastle, too.
Although Newcastle will play at home but their players are in bad situation, specifically for their attackers. There are too many injured players, it will be a big problem for Newcastle to play against Chelsea. I'm sure Newcastle seems difficult to win the match, they probably will play defensively due to the lack of attackers. They will try to get a draw result. With this matter, Chelsea may try to play more offensively. So, Chelsea will have a higher chance to win the match. The home advantage for Newcastle is likely to have no significant impact.
They won't try to tie the game because any team like Newcastle playing at home has the goal to win the game. It doesn't matter whether they play against Luton Town or Chelsea, playing at home as a Champions League participants means you want to beat every other team. But injuries could turn out to be heir weak point and Chelsea as one of the strongest teams on stranger ground might be sniffing a chance here to win some very important points for their way back up in the Premier League table.
