Rio Ferdinand believes Manchester United need to find an upgrade at centre-back to partner Harry Maguire if they want to start competing for Premier League titles.
United lost out on the league crown to rivals Manchester City with three games to spare on Tuesday night after they were defeated 2-1 by Leicester City at Old Trafford.
Although they were without Maguire, who is set to miss the remainder of the Premier League campaign through a ligament injury, Ferdinand believes Ole Gunnar Solskjaer's side are still a defender short if they want to lead a title chase.
