Tactically, Alonso is expected to implement the 3-4-2-1 formation that became his hallmark in Germany. This system aligns well with the current Chelsea roster, who have operated with a back three under previous regimes.
There is also hope that Alonso can revitalise Cole Palmer. After a dip in form over the last 18 months, Palmer’s profile mirrors that of Florian Wirtz, who flourished under Alonso at Leverkusen before his £116 million move to Liverpool. Alonso’s reputation for improving elite talent - including Jeremie Frimpong - is a key reason Chelsea’s board view him as the man to unlock the potential of their high-priced squad.
