The Liverpool defender posted himself on the club's WhatsApp group wearing Chelsea jersey last season.
The move didn't go down well with his team mates but he has come to clear the air by revealing why he did that.
Chelsea needed a win or a draw against Manchester City to enable Liverpool clinch the league title after 30years and on the night Andy Roberson became a Chelsea fan just like every Liverpool supporter and it did ended in celebration as Chelsea defeated Manchester City on the night.
ROBERSON has revealed in his book that the jersey he wore was the one he got from Billy Gilmour and has to wear it cos he can't wait much longer to be champion.
