The Blues then faced some of Europe's biggest clubs as part of the International Champions Cup in a number of venues around the continent.
With the World Cup having ended just eight days before their first fixture against Perth, it left Chelsea with very little time to fully prepare – though it did give players the opportunity to get back into the fold in an energising manner.
Goal brings you your complete guide to the Blues' 2018-19 pre-season and Premier League fixtures, with dates, venues and all you need to know about the preparations.
