While Chelsea manager Xabi Alonso was officially unveiled at Stamford Bridge today in front of the world's media in the afternoon, Cobham was alight with activity earlier in the morning as the Blues boss took training.

It was another busy session, with fitness part of the focus as the squad took part in the 'bleep test' - a test of someone's speed, stamina and focus, with players required to move back and forth between two lines within a certain time.

You'll see the likes of Liam Delap, Romeo Lavia, Cole Palmer and Estevao Willian all involved in the session as we continue our build-up to the first day of the Premier League season, where we'll take on Fulham on Monday August 24. Elsewhere, Joao Pedro, Tosin Adarabioyo and Wesley Fofana were also pictured.
