Danny Mills has claimed that Liverpool full-back Trent Alexander Arnold was “uncharacteristically” poor against Atletico Madrid on Tuesday night.

Speaking exclusively to Football Insider, the former England international suggested that the 21-year-old has been “absolutely outstanding” so far this season, but failed to deliver against the La Liga giants.

The Reds slumped to a 1-0 defeat in the Spanish capital, and now face an uphill battle in the return leg at Anfield as they bid to retain their European crown.

Amongst a number of lacklustre displays, however, it was Alexander-Arnold would caught Mills’ eye for the wrong reasons.

He told Football Insider: “Liverpool were poor by their standards. Trent Alexander-Arnold giving the ball away uncharacteristically, crossed it behind the goal on more than three or four occasions. Liverpool are fortunate they are not three or four behind.

“He’s been absolutely outstanding but I did the commentary and I said I think he’s got my boots on. It was so uncharacteristic, I think every single cross hit the first man, Atletico were clever showing him inside onto his left foot at times to stop him going down the outside.

“Defensive he was caught out in one or two situations, incredibly high press from Atletico – he just had a bad game and that can happen from time to time. Liverpool got away with it.”

Just four of Alexander-Arnold’s 12 attempted crosses were accurate on Tuesday evening, giving him a success rate of 33%.

The England international has featured 36 times for Jurgen Klopp’s men already this season, registering 12 assists in the process.
