Chelsea has indeed transformed under Thomas Tuchel.
The German manager replaced Frank Lampard as the manager in January 2021 and led the club to victory in the Champions League in his maiden season.
The Blues also became Club World Cup champion for the first time in their history this January.
Before Tuchel arrived, Chelsea were languishing at ninth in the Premier League table.
Chelsea defender Marcos Alonso explains how the Blues changed tactically under the German manager.
“We were a very balanced team,” the defender said. “In these close knockout ties, the little details make the difference.
“We were a team in every way. We defended very well, we were an uncomfortable team to play with, we defended all eleven and the small details made the difference.”
“At this point in the Champions League everything is very even and it depends on very small details. Since [Tuchel] arrived, the team took a leap tactically and when it came to defending. We are very happy with it.”
