Trent Alexander-Arnold said he underestimated Marcus Rashford when the pair went head-to-head against one another for the first time.
Playing on the left wing, Rashford scored both goals in a 2-1 win for Manchester United against Liverpool in March 2018, which Alexander-Arnold said was the most difficult experience of his career.
He told The Athletic's James Pearce (h/t Goal's Tom Webber):
"[That match against United was] the toughest in terms of a direct opponent and someone getting on top of me in professional football. I'd say I underestimated him.
