Frank Lampard will deliver bespoke training plans to new recruits Timo Werner and Hakim Ziyech before incorporating them into his first-team squad.
Werner, signed for £54million from Leipzig, and Ziyech, signed for £34m from Ajax, will become Chelsea players on July 1.
They cannot play until next season but Lampard wants to ensure they are fit and fresh when the new campaign starts.

'I'm in the process of arranging that plan,' said the Chelsea manager.
