Mikel Arteta feared for Arsenal after Marcus Rashford's goal because he thinks it's difficult to concede first against Manchester United.
Rashford's outstanding strike opened the scoring at the Emirates on Sunday afternoon, but the game was frantic and three goals followed that effort, with Eddie Nketiah, Bukayo Saka and Lisandro Martinez all finding the back of the net.
With the game level at 2-2 after Martinez's equaliser in the second half, Arsenal searched for a winner and they eventually found a breakthrough in the 90th minute through Nketiah again, who scored with an improvised finish to claim the victory.
