With the conditions of the beginning of the season it is still possible. The points gap with the 4th-placed team is only 9 points, with 33 games remaining it still has a very big chance. But if it can indeed improve the performance in the rest of that game. but if the predictions of new Chelsea players not being able to adapt to English football culture are correct then that improvement is likely to be difficult. This could be Chelsea's transfer failure problem.
A lot of people have already begun to write off Chelsea as not able to perform well this season and are even going ahead to speculate them being relegated after having just played only 6 games. They’ve got a lot more games to play to step up and try to redeem theme selves.
I highly doubt the problems are due to new players being brought in, not being able to adapt to English football culture. Perhaps the strategies deployed by the coaching staff aren’t that effective? They are various reasons on why they’ve failed to improve on their performance.
