Callum Hudson Odoi has endured a difficult period at Chelsea mostly due to a number of frustrating injuries which have hampered his progress at club and international level.
Hudson-Odoi amassed 28 appearances last term but hasn't featured for the Blues since March due to an Achilles injury that developed into a much more pressing issue for the winger.
‘The whole summer I’ve just been trying to build on my strength and my fitness, just focusing on me getting back to being myself really,' Hudson-Odoi told Chelsea's official website.
'I’ve been here (Chelsea's training centre) for the past five out of six weeks with just a one-week break and it’s good to know I've started early to be as fit as possible before the boys came back.
