I think the confidence that Chelsea have when playing big team right is a big win for them, from the previous games the confidence of Chelsea have been everything. Newcastle is a strong team I so much believe in but I don't think playing with Chelsea will be an easy game for Newcastle. The last game Chelsea played with Manchester City has really proved Chelsea is good enough to face any Premier league team, even the game Chelsea played with arsenal is another game to see how Chelsea have improve in their performance this season, I think Newcastle and Chelsea meeting will be another interesting game to watch Chelsea how good they have become.
No one should underestimate Mauricio Pochettino who's currently the headcoach of Chelsea, he was appointed because the owner, Todd Boehly believes he's a prominent coach and stands in the position to deliver the team at this crucial moment. Chelsea is a top club in EPL, that we shouldn't forget in a hurry. Simply because the Blues experience a bad season the previous EPL campaign, they can still bounce back to form this season because mere watching their games, there performance have increase and there's evidence of growth.
Initially, many people underestimated Mauricio Pochettino from the start of coaching at the Chelsea club. Many thought that Pochettino did not have a good strategy in improving Chelsea performance. Indeed, at first Chelsea start the season badly, but slowly Pochettino has begun to know what strategies he should apply to current Chelsea player. This is so that there are no more insults that put too much pressure on the Chelsea coach, at least Pochettino also has to implement good strategies such as when facing the last 2 match of the clubs he brought so that Chelsea can performed better in the remaining matches in the EPL.
When facing big clubs in the EPL, Chelsea also has to prepare their defense when facing Newcastle. Indeed, Newcastle is not an easy opponent, but among the clubs that Chelsea just beat, Newcastle is still not thats tough when compared to the last 2 club (Tottenham and Manchester City)
I don't really agree with such an ideology of playing very well when you meet big club and giving points away to smaller teams, this to me seems like inconsistency and mediocrity on the side of the manager. He has to replicate the same winning result everytime and everywhere if he must secure a place for Chelsea in the European competitions because if he fails to do this then his job could be on the line.
