Liverpool defender Trent Alexander-Arnold admits that he underestimated Marcus Rashford in their duel last year.

Rashford played on the left wing that day, and played a decisive role for his team in the win at Old Trafford.

United claimed a 2-1 win, with Rashford tormenting Alexander-Arnold for most of the game.

But the young full back believes it was a learning experience that helped him develop.

"[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," Alexander-Arnold said of Rashford to The Athletic.

"It was a massive learning curve for me. It was something that I hated happening. As a Liverpool player, it's probably the worst game of the season to perform like that. But when things like that happen you have to learn from them.

"It was a wake-up call. You hate days like that. You don't want to experience that. You remember how it felt and that makes you try everything you possibly can to ensure you don't have another one like it."
