Liverpool legend Jamie Carragher feels Manchester United are paying for their poor transfer policy.
United shipped five goals at Leicester City yesterday.
Carragher said: "Manchester United were the biggest spending team in the Premier League and haven't even bought a proper defender.
"To spend that much money and not bring in a top class defender is mis-management at the end of the day.
"You look at Liverpool last season and the goals they conceded which ultimately cost them the league, United look vulnerable like that at the back this season.
"They look like the United of old in terms of their attacking play and are showing real pace and quality in that department for sure, but defensively you have to question them."
