Borussia Monchengladbach defender Andreas Christensen expects to do preseason with Chelsea.
The Dane is in the second season of a two-year loan with Gladbach from the Blues.
Christensen admits he expects a 'make or break' preseason this summer under Chelsea boss Antonio Conte.
He told BT: "I have not had a holiday for a long time.
"But if I go back to England in the summer and want to impress the coach in the preseason, I cannot be completely broken and miss the first weeks of training."
