London - Manchester United manager Louis van Gaal hailed Marcus Rashford's startling self-awareness after the 18-year-old striker's memorable goal inspired his side to FA Cup victory at West Ham United.
Rashford broke the deadlock in the 54th minute of Wednesday's quarter-final replay, shimmying inside James Tomkins and arcing an unstoppable shot into the top-right corner.
Marouane Fellaini added a second and although Tomkins replied late on, visiting goalkeeper David de Gea brilliantly held West Ham at bay to send United into the last four for the first time since 2011.
Hailing Rashford, who has now scored six times in 11 games, Van Gaal said: "He's very focused on his work and that I admire when you are so young.
"There's so much attention now because he is scoring so many important goals and you can cope with that attention and focus on your next match.
"And when you have criticism, he can cope with criticism also and he can say about himself, 'Yes manager, you are right, and I have to do that and that'.
"I think it is fantastic because there are not a lot of players that can see their self-image in the match."
After months of intense speculation about his position, Van Gaal will lead his side out to face Everton at Wembley later this month knowing that he is two victories from a first trophy as United manager.
The Dutchman came in for a fresh wave of criticism after Sunday's 3-0 defeat at Tottenham Hotspur, but he said that his record meant that he was worthy of the patience afforded him by the United hierarchy.
"I do my work, I do my utmost best and everywhere I have worked, I have won something," he said.
"A lot of things have been changed in all the clubs where I have worked and because of that I am here. I am selected by Manchester United because of that. Not because I am a lousy trainer or manager."
