Video: Louis van Gaal says he is a 'happy coach' after Manchester United beat Watford

Louis van Gaal continued his lucky streak of alighting on solutions to problems through luck in having in hand forced by injuries. This time Memphis was called into action as a striker, where he scored the opening goal for Manchester United against Watford in their 2-1 win.

He then claimed that he had identified Memphis's best position, despite not trying him there all season while Wayne Rooney utterly stank out the whole side for three months.

Van Gaal said after the match:

In the first half, Memphis was superb, like Jesse Lingard.

I think also this role for Memphis is the best one for him. He played it also in the World Cup for me when Van Persie and Robben were injured so I knew he could do it.

Jesse also was fantastic and we have created a lot of chances thanks to those two.

Which indicates that Van Gaal believes that Rooney is playing better than Memphis did today, which he plainly is not. It will be interesting to see if Rooney returns against PSV in the week when back from illness, with superior options being plain in each of his proposed positions. The injury to Ander Herrera is another lucky blow for Van Gaal, giving him an excuse to keep Rooney in at number 10, another position he cannot play.

Van Gaal was also lucky to recover after his negative substitutions and witless change in formation halfway through the match, with Bastian Schweinsteiger forcing a late winner. As US residents can see below with this clip from NBC, Van Gaal declared himself, 'happy.'
