Roma midfielder Nemanja Matic has hit back at Roy Keane and accused of him not 'understanding that football has changed.'
It comes after Keane criticised a comment made by Matic in April that Chelsea, United and Benfica would always 'be in his heart.'
'Where's the standards at the club?' Keane asked at the time on Sky Sports. 'Matic's talking about I'm leaving, I've had a great time, Man United will always be in my heart, oh and Chelsea as well, oh and Benfica don't forget them, they all can't be in your heart.
