Last season Chelsea had Cristopher Nkunku and Nicolas Jackson as their strikers with Jackson leading the pack as the first choice striker so it was understandable if Maresca declined ideas of bringing in another striker but both players are already tipped to leave the club this summer and replacements have already been made for be due.
Chelsea have enough option at striker position indeed Nicolas Jackson have inconsistent performance but new recruitment João Pedro have very promising performance after one goal and made two assists of two games. Chelsea's head coach Enzo Maresca not really scare about striker position and recently youth players Estêvão have brilliant performance when Chelsea beating West Ham United last match.
Fully potential striker having by Chelsea right now and Enzo Maresca have planning for selling Jackson or Nkunku have loss regular position with Chelsea right now. Not close chance for Chelsea signing new striker because window transfer opening still left few weeks later and enough to get the top striker indeed Maresca not publishing yet for awhile need new striker.
Chelsea for me has a really strong team, as well as having enough quality strikers. Joao Pedro was a really good buy because this is a very strong and promising player! He was their dragging force to the Club World Cup victory.
So Enzo Maresca should already be happy with his strikers. I had heard that Nkunku would leave Chelsea but no team seems to have made a concrete request
