Roma midfielder Nemanja Matic has hit back at Roy Keane and accused him of not 'understanding that football has changed.'
The Serbian moved to the Serie A club on a free transfer in the summer after leaving Manchester United at the end of his contract.
Upon making the switch, he declared that his former clubs United, Chelsea and Benfica would always 'be in his heart' - a comment which frustrated Keane.
'Where's the standards at the club?' Keane asked at the time on Sky Sports. 'Matic is 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.
