The France defender helped the Reds keep a vital clean sheet in the first leg of their Europa League last-16 clash as Daniel Sturridge and Roberto Firmino scored against United.
Sakho made an unconvincing start to his Liverpool career after a £16m move to Merseyside from Ligue 1 side Paris Saint-Germain in 2014.
However, the 24-year-old has impressed since Jurgen Klopp took over the reins at Anfield despite a high turnover of centre-half partners.
Burnley midfielder Joey Barton, who played against Sakho during his spell at Marseille, tweeted his thoughts on the unorthodox Liverpool defender.
Mamadou Sakho is the most unorthodox, efficient, unbalanced, effective defender on the Planet.

Having read Barton’s tweet, England legend Gary Lineker also ousted himself as a fan of Sakho’s unconventional defender.
@Joey7Barton couldn't agree more. First thoughts were that he was hopeless, but actually he might just be brilliant.
