The United rumour mill never stops and over the summer, a name to crop up on more than one occasion was Nemanja Matic. The midfielder is in the final year of his contract, although there is a plus-one option to extend his stay, and talk naturally began to turn to his future after Jose Mourinho’s departure. The 31-year-old was brought in by the Portuguese as one of his favourites, having worked together previously at Chelsea. With Ole Gunnar Solskjaer turning to youth, there have been some doubts over Matic’s long-term place at Old Trafford. Some discussion has even risen regarding whether the club should in fact keep the Serbian player next summer or let him go. But on Thursday night he led the team out as captain – and supporters got to see him in a new leadership role, setting the example to younger teammates.
