Trent Alexander-Arnold thinks Liverpool teammate Neco Williams can become 'world-class'.

The 19-year-old made his Premier League debut against Brighton on Wednesday.

"It's his Premier League debut, it's his first start, so it's something he'll never forget.

"It's obviously not gone the way that he wanted it to, but he's a young lad and he'll learn from it.

"He's shown that mentality over the last 12 months, so as players and the manager we won't have any concerns about the way he's performed.

"He's a young lad, he needs to make mistakes to learn from them, so he'll learn from then and progress.

"He has shown signs of being a really, really talented player. With the right attitude, which he's got, he has got the potential to be a world-class player."
