VIDEO: Louis van Gaal sarcastically congratulates Gary Neville for United victory

Louis van Gaal was obviously in a great mood following Manchester United's win over Liverpool.

So much so that he offered congratulations to Gary Neville during the former United player's work with British broadcaster Sky Sports.

Perhaps van Gaal was taking a dig at the television pundit following Neville's criticism of Manchester United's early-season defensive woes.

Neville compared Untied's defense to a pub team following a pair of narrow victories in December.

To which van Gaal replied: "He can say everything because he is an ex-legend, but as an ex-legend, or a legend, you have to know what you are saying."

It appears the Dutch boss finally got his pay back.
