Zouma became a first-team fixture for Chelsea last season, occasionally keeping club captain John Terry out of the starting XI.

But, having risen to prominence in the latter stages of Jose Mourinho's tenure, Zouma picked up an injury early in Guus Hiddink's caretaker spell - leaving the field with a knee injury during a 1-1 draw with Manchester United.

The French defender was able to complete some parts of training in Austria ahead of Chelsea's second preseason friendly against Wolfsberger on Thursday (AEST).

New manager Antonio Conte was also able to get a first look at Michy Batshuayi, who joined up with the squad late on Sunday and was thrown straight into training on Monday morning.

Batshuayi was signed from Marseille for a reported fee of $58 million this month.
