I thought this was just a lucky win for Chelsea because several times Brighton players actually had the chance to score but were thwarted by Robert Sanchez and after that in the second half Chelsea managed to score goal with pride.
Imagine that there 4 opportunities that I counted for Brighton to score goal and if all the opportunities can produce goal, I think Chelsea will lose badly against Brighton with a score of 4 which they failed to use well and I see Pochettino very proud of yesterday match even though it was luck that can be thwarted by the Chelsea goalkeeper.
Chelsea's win yesterday was a needed win in order to keep the heads of Chelsea up above the water. If they had lost yesterday's match, their moral would have been very down and their confidence level reduced. In as much as we are expecting Pochettino to master the Chelsea system and start doing well, having consecutive losses would do more harm than good to both Chelsea as a club, the coach and the players.
With the performance of Chelsea in that match, it isn't obvious that Chelsea has escaped their epileptic performance for this season yet.
It was just a match in the EFL Cup and of course, even though Chelsea managed to win in the match it does not guarantee that Chelsea can get good results in the Premier League too. So yes, let Chelsea get the victory in that match because of course, with the victory it is also maybe that it will make the morale of Chelsea players even better when playing in the Premier League. Because after all, at least improving Chelsea's position in the Premier League standings is more important, than win in the EFL Cup match. Because yes, if Chelsea do not manage to improve their position in the Premier League standings, then of course this will make Chelsea feared to fall into the relegation zone.
