Trent Alexander-Arnold suffered a moment to forget just four minutes after Liverpool returned to the Premier League after the international break.
The right-back has been left out of the England squad for their UEFA Nations League matches with Italy and Germany, leading to widespread debate over whether he would make the world Cup.
Unfortunately, based on his debut against Brighton, he could still have some work to do.
New manager Roberto De Zerbi’s side got off to a good start in the clash at Anfield with Danny Welbeck collecting the ball at the edge of the penalty area.
He sent a pass to Leandro Trossard who wrong-footed Alexander-Arnold at the edge of the box, putting the defender on his back in the process.
With a free shot on goal, Trossard placed a clever effort beyond Alisson and into the bottom corner of the net to put Brighton ahead with just four minutes on the clock.
With Alexander-Arnold needing good performances to step into England’s fold, he will be very disappointed with the way they conceded that opener.
However, the 23-year-old was again at fault as Brighton went 2-0 up 14 minutes later.
Alexander-Arnold lost possession to Welbeck, who again played Trossard and another well-executed effort made it 2-0 against the Seagulls – with the striker becoming the first visitor player to score a first-half brace -time at Anfield since October 2008.
Reporting for talkSPORT, Matt Jones said: “Liverpool 0 Brighton 2 and it’s Leandro Trossard who has it again.
“We were talking about Trent Alexander-Arnold and it was his touch that gave Danny Welbeck the ball. Welbeck then finds the ball in the middle of the box where he picks off Trossard who slams the ball into the same corner where he scored the opener.
“Alisson will be really disappointed to be beaten from this angle and Liverpool are in absolute disarray. They really have a mountain to climb.
The Reds quickly pulled one back to make it 2-1 through Roberto Firmino, with the goal awarded after a lengthy VAR break after initially being flagged for offside.
But Jurgen Klopp’s side still have work to do to turn things around in the second half.
