New Chelsea manager Xabi Alonso said Monday he has found "good energy" at the club but stopped short of defining what success would look like in his first season.

The Spaniard officially began the job on July 1 and will take charge of his first competitive fixture in Sydney Tuesday when they face Western Sydney Wanderers.

He faces a huge task to get Chelsea back in the running for major honors after their disappointing 10th-place finish last season and failure to make Europe.

They last won the Premier League a decade ago, under Italian manager Antonio Conte.

Alonso, who has made a series of pre-season signings headlined by Morgan Rogers from Aston Villa, said he liked what he had seen so far.
