Cape Town - Jamie Carragher has described Manchester United's transfer dealings as 'mis-management' in his scathing report on the club.
The Daily Mail report that Carragher highlighted the reason for United's dismal start under Louis van Gaal.
The ex-Liverpool player was working for Sky Sports as a pundit during the Red Devils surprise loss to Leicester City.
United lead 2-0 and 3-1 before conceding four consecutive goals to the English Premiership newcomers.
"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." said Carragher.
"'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.
It was the first time that Manchester United had lost an English Premiership game after being two nil ahead while the Foxes became just the sixth side to score five past Manchester United in the Premiership.
Manchester United host West Ham on Saturday, September 27 with defenders Jonny Evans (injured), Phil Jones (injured) and Tyler Blackett (suspended) all out of the clash.
