Chelsea lost 1-0 to Japanese side Kawasaki Frontale in a pre-season friendly on Friday.
Brazilian striker Leandro Damiao scored the winning header two minutes from the end of the match.
Pre-season results normally do not mean much to managers but Frank Lampard may have been a little concerned by the lack of chances the Blues created.
Lampard had an experienced starting XI at the Nissan Stadium with senior players like Cesar Azpilicueta, David Luiz and Marcos Alonso in defence.
New permanent signing Mateo Kovacic played alongside Jorginho in midfielder while Pedro also started.
N’Golo Kante was not fit enough to even make the bench in Japan while Kepa Arrizabalaga and Tammy Abraham missed the game through illness.
