An 11-second goal from Eriksen opened the scoring, before a Jones own goal sealed the win.
Sanchez made his Premier League debut for United, but his second half showing was far from great.
“He worked hard, but again the transformation the game had, the game was not for him,” he said.
“In the second half, I tried to give him a position where he could be closer to [Romelu] Lukaku but then he felt the need to drop too much to organise.
“But he gave everything, good effort and this is a good feeling for me to know that the player is available with that spirit.”
