(CNN) -- Last weekend Louis Van Gaal was hailing the beginning of a "new era" at Manchester United after a rout of QPR. Sunday saw a sobering reality check for the Dutchman and his expensively-assembled "galacticos" as the English Premier League powerhouses surrendered a 3-1 lead to lose 5-3 to newly-promoted Leicester City. It had looked an improbable scenario at the King Power Stadium as United's attacking prowess was on full display with Radamel Falcao setting up Robin van Persie for a headed opener before record signing Angel Di Maria made it 2-0 with a delightful chip. The first danger signs came after Leicester's new talisman Leonardo Ulloa headed home to reduce the deficit, but when another United summer signing Ander Herrera re-opened the two-goal with a clever back heel, the three points were there for the taking.
