London: Michael Carrick admits this could be his last season playing for Manchester United. Carrick has started only once in the Premier League this term, with Jose Mourinho so far preferring Ander Herrera, Marouane Fellaini and Paul Pogba at the base of his midfield. It means 35-year-old Carrick has been used primarily in cup competitions, twice in the EFL Cup and once in the Europa League, although he did start United’s last league game against Swansea.
