Surprisingly Chelsea’s new signing Nicolas Jackson has been showing potential for Chelsea in the pre season games. He already has 3 assists and a goal recorded for the team, could this mean Chelsea have got themselves the perfect signing this summer? It’s still early to judge but I am already seeing good improvement for Chelsea under Pochettino. I hope this improvement will remain as the season kicks off next month because most times teams do well in the preseason and flop when the season starts.
Indeed. It may be too early to judge Chelsea already sign the right player and probably gets positive impacts on its performance in the next season. However, it is true that the good performance of Nicolas Jackson during the pre match season, raise a hope for us to see a better performance of Chelsea in the future. He already contributed a lot during the pre season match, it indicates he is ready for the next season. Let's hope that it is not only Nicolas Jackson, but the whole players of Chelsea are ready to give their best as well. Considering the results of pre matches season, we can expect Chelsea will be better under Pochettino's management. 
Pochettino is a coach who understands strategy and is able to build a better quality team. He has worked with Tottenham for several seasons and he has also worked with PSG. Pochettino will slowly restore the quality of Chelsea's game in the Premier League so they can compete again for the title. His initial job was difficult because he had to build Chelsea very carefully, his experience can help him to speed up his recovery.
Pochettino's plan for Chelsea is very clear, he wants to return Chelsea to the peak of its performance. But I hope Pochettino won't swallow his own saliva after making that statement, it's because Chelsea have a lot of players who still haven't fully adapted so far.
