The core of Chelsea team is still intact except the departure of Rugider to Real Madrid other players are fringe players who Tuchel feels are not needed in his plan for next season, Lukaku had not live up to expectation and very inconsistent in his performance, Ziyech had not been a regular first team player, Werner has been wasteful in front of goal despite given enough playing time.
Chelsea needed few more signings a good defender to replace Rudiger and a new striker, the team midfielders is enough have quality players like Kanye, Mount, Loftus-Cheek, Jorginho, Kovavic etc.
With the amount of games played each season in different leagues, main players will get exhausted, there will be injuries... You cannot count only on them to maintain good results all over the season. Ziyech for example played like half games, Werner wasn't that useful. Lukaku performance was way under his ordinary level.Chelsea needed few more signings a good defender to replace Rudiger and a new striker, the team midfielders is enough have quality players like Kanye, Mount, Loftus-Cheek, Jorginho, Kovavic etc.
There will be a destabilisation of the team with these changes but what counts more is to see new signing that will turn to be useful next. Will it be the case? We will see.
