Rio Ferdinand believes it would be a "nightmare" for Manchester United if Liverpool and Manchester City were to share all four trophies they have competed for this season between them.
The former United man made the admission after City joined Liverpool in booking their place in the quarter-finals of the Champions League on Wednesday evening. City were held to a goalless draw by Sporting Lisbon at the Etihad Stadium but progressed after winning the first-leg 5-0 in Portugal last month.
Liverpool qualified for the quarter-finals after edging past Inter Milan just 24 hours earlier. They lost the second-leg 1-0 at Anfield but went through 2-1 on aggregate after their first-leg win in Italy.
