Maybe Chelsea is only slightly ahead with their current performance but that doesn't mean they can win easily against Newcastle.
We know Newcastle is also a difficult club, so no one is expecting the match to be a easy win for Chelsea. We all know Chelsea have been playing well lately, but I am sure they are still going to give Chelsea a tough time. But if we can compare the way the two clubs have been playing lately, Chelsea should be able to win the match. Newcastle lost their last two matches, the last one being against Bournemouth and their match against Dortmund in the Champions League. But most people didn’t expect Chelsea to win and draw their last two matches. Chelsea played a draw against Manchester City, which was very surprising to everyone, and they won against Tottenham. With Chelsea's performance, they should be able to win the match.
Chelsea last two matches very impressive, and perhaps this will make the Blues squad more confident against Newcastle. Apart from that, Chelsea also seems to have found their rhythm, because in 8 matches in all competitions the Chelsea team only one lost. This also proves that their performance already improve, so I'll probably favorite Chelsea in that match, and will bet on them.
Meanwhile, on the other side Eddie Howe may will be not too much pressure squad Newcastle to got winning against Chelsea, and in my opinion maybe they will be play safe because there is an important schedule in the UCL which requires Newcastle players to be fit.
A lot have changed with Chelsea in the last few games and even since the current season started, Chelsea has been in a high recovery mood that has this a lot about the club and their readiness to reclaim their lost glory this season, and Chelsea's remarkable records in the last few matches is a pointer to what we can expect from the club in the remaining weeks and months that remain for this season to get to an end, and even if Chelsea can't take the first spot, but at least there will finish this season among the top 5 top clubs for this season..
So let's see how things turn out to be for Chelsea in this season since they already started on a good note for this season.
