Too much hope for Pochettino when he's not yet proving anything for Chelsea or other clubs he had managed, there are no difference between Pochettino and Potter based on their past experience.
The different thing if pochettino has ever bought totenham to finish as runner up years ago in EPL. Pochettino has also ever win farmer league a few times with PSG while potter has zero result in EPL and french league. Pochettino is not as good as it used to be but at least people shall give chelsea a try. We can judge him based from the result in pre season matches. Chelsea may not perform as good as what expected by people but as long as it will not be even worst when lampard was managing the club. it's fine.
Only playing for one league don't make Chelsea would have a good performance, it's just matter of the coach who's can manage the club and know the limit of his players. The thing is if Chelsea performance is still bad, the problem is from the players, but unfortunately their veteran players have joined other clubs and there's no way for Pochettino or new coach to get back all of their veteran players.
That's true. That's why people shall be patience waiting for the result from pre match before they will start their judgement for the performance of chelsea under the new coach.
I remember when spurs has also bad time under him. It's too early to think chelsea will bring something new.
