A full list of Trent Alexander-Arnold's mistakes since the CL final makes for damning viewing

In Monday's 2-1 defeat to Manchester United, he was run ragged by Anthony Elanga and caught out for Jadon Sancho's opener.

Saunders thinks Alexander-Arnold's poor form extends as far back as last season's showdown with Real Madrid in Paris.

The 23-year-old was the wrong side of Vinicius Jr., who ghosted in behind and managed to score the only goal of the game.

Saunders said: "I mean Trent, I don't know... don't get me wrong going forward he's world class. But defensively, he's getting found out. [Aleksandar] Mitrovic come over the top of him at Fulham. Vinicius Jr. in the Champions League final did him at the back post.

"He gave the ball away for the goal against [Crystal] Palace. Last night, he jogs out to Elanga, gets done with a one-two and then walks.

Former Reds striker Saunders believes Alexander-Arnold played a part in the home side doubling their lead eight minutes after the restart too.

The 23-year-old attempted to whip a ball into United's box but it was headed away by Raphael Varane.

Jordan Henderson failed to control the header and it allowed Anthony Martial to play a lovely ball through to Marcus Rashford, who was galloping into space.

Rashford made no mistake from close range and Saunders suggested Alexander-Arnold could've offered more cover for Joe Gomez in central defence.

He continued: "The second goal, he hits a diagonal into the box and loses it, doesn't sprint back. Gomez is left in the channel stranded.

"I think there's a combination of injuries, some bad defending, van Dijk is getting a bit of stick but he's playing with a different player every week and with a high line. To play that high line, you have to have a telepathic understanding."
