Marcus Rashford, who became an honorary doctor this week, showed coldness and placed 1-0 in extra time in the first half.
At 1-0, Crystal Palace had a goal failed after VAR review for two minutes, which was so tight that it was even difficult to distinguish with lines laid out. Palace coach Roy Hodgson looked dissatisfied to say the least.
Instead, Anthony Martial punctured the match with his 2-0 goal in the 78th minute.
"Had to work twice as hard to win today"- Every match is an important match for us now, we scored goals we wanted before the meeting with Southampton (2-2 last) but the last two matches have been difficult for us. We had to work twice as hard to win today, Rashford says to BT Sport.
The Swedish national team defender Viktor Nilsson Lindelöf played the entire match.
Three teams, Chelsea, Leicester and Man United, are fighting for two CL places, where the top four in the league go. Liverpool and Manchester City have already secured their CL places.
