With Jamie Butler injured and Ross Worner cup-tied in the FA Trophy, Ziger is likely to go straight into the side for the U’s trip to National League North high flyers Spennymoor Town tomorrow.
The 17-year-old shot stopper, who has represented Croatia at under 17 level, signed a professional contract with the Blues this summer.
Ziger made twelve appearances for Chelsea’s Under 18 side last season and kept a clean sheet in the FA Youth Cup semi final second leg against Birmingham.
