Chelsea finished 12th in the standings last season, Pochettino came to Stamford Bridge and took over leadership by inheriting various problems within the club. Club officials have adopted a policy of major overhaul of Chelsea body, prioritizing the recruitment of young players who apparently lack experience, completing the complexity of the Blues current decline in performance. I think everyone in the Chelsea squad is under a lot of pressure, especially Pochettino.
The worst consequence now is that Pochettino could be fired, if he is not able to improve Chelsea performance. Player adaptation seems to be in place, Pochettino must immediately look for other formulas and tactics to make the Blues improve. With the absence of European competition and the lack of matches played, Pochettino should be able to do it quickly and focus completely on the EPL.
Have to face consequence when focus signing young player lack experienced exactly playing on top level competition such as Premier League, for Chelsea fans need more patience waiting progress with young players recruitment and they need more time for adapting well with most competitive league around the world. In this season, Chelsea performance still not consistent yet when some time win and other match have loss until dropped to 11th position awhile from 7 matches.
Actually Pochettino under pressure right now with Chelsea have bad performance, absence in European competition should be advantage for Chelsea but they can't manage well without busy schedule match for improving their performance in Premier League.
