I agree with you and for me, the result is final. The match has turned 1-1 at the very extra time, no side seems better, but if one looks at it extensively, Chelsea is better than Cryptal Palace, the issue with them is that they lack the attacking as needed. They also blew away the win of the first half when Crystal Palace scored nothing until the second half. I don't see any goals coming for either side till this match ends with what they are both playing.

Chelsea football team should attack in last minutes to win this match but they didn't attack in this match and after that we saw match was ended with draw. We want result of that match but that was good performance by Crystal Palace team because they gave all efforts to win this match and after doing 1 goal they defended very well and every time they saved the goal. The goalkeeper of Crystal Palace team is good player and he has mindset of winners and he will be winner of next matches because he is looking in good form. Jackson did first goal in this match and after that no player became successful to do next goal and that was big reason behind the result of draw match.
In the end of the match Crystal Palace just parked the bus in their penalty area and apparently Chelsea just did not have enough skill or luck to bring the match to victory, and the first half Chelsea played well and it was obvious that Maresca is trying to establish a new style of play for Chelsea, almost does not change the squad and in general playing the same players, but in the second half with Crystal Palace it was obvious that the team ran out of ideas and can not come up with anything new in a situation where the opponent almost the whole team plays in defense.
In addition, standard positions also remain Chelsea's weak point and it seems that not all Chelsea players understand how to act in such situations.
For example, after playing a standard, the ball fell to Eze and it was unclear why he was alone in the penalty area with the ball and none of the Chelsea players were around.
