Caroline Wozniacki has broken her silence after Rory McIlroy confirmed they called off their engagement.

In a statement yesterday, Rory said he was to blame for the split after realising he wasn't ready for marriage.

Today, Caroline has tweeted to say she's having a hard time but is glad she is a Liverpool; supporter because she will 'never walk alone'.
