Christopher Jullien has apologised to Celtic fans after his "nervous" showing against Livingston led to a 2-0 defeat at the Tony Macaroni Arena.

The Hoops defender had a torrid afternoon against Lyndon Dykes and Scott Robinson as the pair both scored to sink the Celts.

Jullien had a particularly difficult time of it up against the physical strikers and even went as far as to thank them for giving him the jolt he needed.
