Tomas Kalas has jetted off with Chelsea on their pre-season tour of China and Signapore as doubt surrounding his future continues.

Fulham are believed to be in a battle with Hull City for his signature after the Czech international returned to his parent club after a successful season at Craven Cottage.

The 24-year-old has one year remaining on his contract at Stamford Bridge with both Fulham and Hull having been in talks with his representatives over where his future is, but at the moment no progress has been made.

With Chelsea's current transfer policy, however, it looks likely that Kalas will sign a new deal before heading out on loan once again in similar fashion to Lucas Piazon's return to Fulham.

Chelsea face Arsenal in China before facing Bayern Munich and Inter Milan in Singapore in three prestigious freindlies.
