"To do my best, to do the things I have been doing in my last few games and on the training ground as well," the smiling match-winner revealed.
"I try to do that every time, to help my team with a lot of effort and to do the things I have done today."
United went 2-0 down early in the second half, but eight minutes later Paul Scholes picked out Chicharito with a long pass from the halfway line and the Mexican made his first impact on the match at a crucial time.
"I think it was very important. Sometimes you can score late as well and get the three points and that’s part of the game, but thankfully we recovered quickly after they got the second one.
"In the history of Manchester United, we never want to give up until the end. The game is for 90 minutes and you need to play until the last minute.
"We need to improve because we’re conceding a lot of goals but thankfully we got the three points.
"I have a lot of best moments with this club and this is one of them."
