That’s the opinion of Martin Keown.
The Reds could drop to second in the Premier League table when they take on their neighbours from across Stanley Park at Goodison Park (4.15pm), with rivals Manchester City facing Bournemouth this afternoon (3pm).
Liverpool have not lost to Everton since October 2010, going 18 derbies unbeaten since then, but the Toffees will hope to avenge their 96th-minute loss to their bitter enemies back in December.
Everton have won just five of 16 games in all competitions since then, losing nine times.
At Goodison, they have won just one of their last seven in the top flight including four defeats in their last five but the home supporters will be sure to create a white-hot atmosphere as Marco Silva’s side look to put a dent in Liverpool’s hopes of winning a first title since 1990.
This contest has been suggested as Liverpool’s biggest hurdle between now and the final day of the season on May 12 and they come into the game off the back of a huge 5-0 thrashing of Watford at Anfield.
Right-back Alexander-Arnold made his first league start in a month-and-a-half against the Hornets and became the youngest player in Premier League history to provide a hat-trick of assists, all of which came from crosses.
And Keown thinks Alexander-Arnold will be key to Liverpool’s hopes of doing the double over Everton – even likening the England international to club legend and ex-captain Steven Gerrard due to his ability to deliver top-class deliveries from wide positions.
“Sometimes, you only realise a player’s true value when they are out of the team,” Keown wrote in his Daily Mail column.
“During Liverpool’s recent dip in form, they desperately missed Trent Alexander-Arnold’s creativity.
“He has returned just in time to make them believe they can win the title.
“This young man plays without fear. When he cuts loose, opponents do not have much time to stop him.
“Everton are vulnerable from crosses and if they do not stop Alexander-Arnold on Sunday, Liverpool’s fearsome forwards will be queuing up to put the ball in the net.
“The quality of his delivery is sublime. Alexander-Arnold has natural talent for striking the ball, bending his body to generate maximum whip and pace.
“He reminds me of Steven Gerrard in the way he crosses, with such accuracy and venom.”
Klopp, meanwhile, revealed after the Watford win that Alexander-Arnold – who will likely be the only Liverpool-born player in their squad against Everton – took home the match-ball for his trio of assists.
The German said: “The Watford game was exceptional.
“I don’t think I’ve ever been part of a game where someone had a hat-trick of assists. It was special.
“Trent got the matchball – he wanted it so he got it. It was really cool and let’s try to do something like that again.”
