Klopp 'angry' as Swansea shock sorry Liverpool
Swansea 1 - 0 Liverpool
Swansea produced one of the shocks of the season as Virgil van Dijk's Premier League debut for Liverpool turned into a nightmare.
Alfie Mawson struck the 40th-minute goal for bottom club Swansea, pouncing on a poor Van Dijk clearance from a corner the £75m record signing should not have conceded.
Liverpool came in unbeaten in 18 games and on a high after ending the unbeaten record of league leaders Manchester City, so few saw this coming.
It was a frustrating night for Liverpool but they almost rescued a point in stoppage time when Roberto Firmino's header came back off a post.
Jurgen Klopp's side dominated possession and territory, but their usual invention and spark were badly missing, with 24-goal man Mohamed Salah suffering a rare off-night.
Klopp, whose side beat City 4-3 in their previous match, said: "Last weekend is not what I'm interested in.
"We are frustrated. I'm frustrated, I'm angry, because it's not necessary what we did here. But we cannot get the points back. It feels bad.
"We didn't keep the positions we wanted to be in. We wanted to do it differently, it didn't happen on the pitch.
"The clearest chance we had in the last second, I don't know how that didn't go in.
"That wouldn't have made the game any better. At the end it was not good enough."
Swansea remain bottom of the league - on goal difference from West Brom - but it is now only one defeat in six games under new manager Carlos Carvalhal.
Carvalhal said: "If you put Formula One (cars) in London at 4 o'clock in traffic, (they) will not run very fast. That must be what we do against Liverpool - make them play how they don't like."
There was a lack of intensity about much of Liverpool's play, even if Swansea goalkeeper Lukasz Fabianski had to bravely block at the feet of Sadio Mane in the eighth minute.
Swansea did break the stranglehold for Jordan Ayew to race onto Sam Clucas' pass and find the Liverpool net, but referee Neil Swarbrick had correctly ruled that the ball had crossed the line and awarded a corner.
Van Dijk glanced Alex Oxlade-Chamberlain's corner narrowly wide and then released Salah, but the Egyptian could not control his difficult volley.
But Liverpool were stunned five minutes before the break.
Van Dijk made a hash of Clucas' corner and his attempted clearance struck Federico Fernandez to fall perfectly for Mawson, who swept home.
There was little respite for Swansea as Liverpool began to crank up the heat in the second half, but to no avail.
Liverpool kept coming with Danny Ings, on as a substitute, almost scoring, Joe Gomez firing wide and Salah shooting over.
But Swansea held on for their fifth league win of the season.
