Rio Ferdinand has said that Liverpool's expectations are rising - - but expectations are nothing new for Manchester United and their manager Jose Mourinho.

United host Liverpool in the Premier League at Old Trafford on Sunday, looking to cut the gap behind Jurgen Klopp's second-placed side from five points down to just two points.

Former United defender Ferdinand believes Liverpool's weakness is their defence -- although the Merseyside club have the attacking power to outscore sides.

"With the team that Klopp is building, the expectations are rising around Liverpool," he told the club's official website. "Expectations are nothing new for Jose Mourinho or United."
