This nonsense again? LVG was a great character, and 20-years ago, a great manager too. By the time he arrived at United he was well past his sell by date. Your ridiculous attempt to credit LVG for United's victory over Tottenham was embarrassing. LVG tried, failed and ultimately abandoned 3 at the back. He could not make it work and gave up. Attempting to use LVG's failure for a victory under another manager, 2-years later is absurd.
LVG bought and sold poorly as United manager. He sold players he might have been better advised to keep and brought in only one great player in Martial, some decent players in Herrera and maybe Rojo, some squad players in Blind and Romero and a string of expensive disasters from Angel Di Maria, to Falco via Morgan Schneiderlin, Memphis Depay, Luke Shaw, Victor Valdes and Bastian Schweinsteiger.
Let's give him credit for turning to Rashford. There were other options, but LVG took Giggs' advise and gave him a shot. What he ultimately left though, was a team without a spine and who's only success in 2-years was scraping past Palace in an FA Cup Final and a string of great results against some top sides in his first season. Those results, it would later turn out, were a complete anomaly and were the result of using another system which he would again later abandon.
I liked LVG, he should go down as a great manager, but not for Manchester United. The 4 signings Mourinho made when he started were key, as were two of the three he made this summer.
I know you're like a dog with a bone on this point, but it's time to let go.
