Mo Salah scored a hat trick to secure a 4-3 victory for English Premier League champion Liverpool in a breathtaking opening day match with Marcelo Bielsa's swashbuckling Leeds United side at Anfield on Saturday.

The away side came from behind three times and looked set to be earning a precious point until Salah converted an 89th-minute penalty after Leeds' club record signing Rodrigo fouled Fabinho to concede the spot-kick.

Promoted as champion from the English second flight last season, Leeds put on a command performance to push Liverpool all the way in a match that would have graced a packed stadium rather than a scattering of squad players and officials.

Egyptian star Salah, who looked sharp throughout, proved the difference, putting his side in front with his first successful conversion from the penalty spot after four minutes and completing the first-half scoring with a laser-like finish to edge his side 3-2 ahead in an extraordinary five-goal first half.

Leeds, playing with the high-tempo pressing style so typical of Bielsa's sides, levelled at 3-3 on Mateusz Klich's 66th-minute goal, which he started and finished. But Leeds could not hold out under intense pressure from Jurgen Klopp's men.

Returning to the top-flight after 16 long years, Leeds could scarcely have made a poorer start as new signing Robin Koch conceded a penalty as Salah's shot deflected from his knee onto his outstretched arm.

Liverpool went ahead again eight minutes later as Virgil Van Dijk powered home a header from an Andy Robertson corner but the Dutch defender was at fault soon afterward for the second Leeds equalizer.

He miscued a clearance and Patrick Bamford was on hand to score neatly to make it 2-2.

Both sides were showing defensive frailty and it was another indifferent clearance from a free kick that afforded Salah the opportunity for his second goal, controlling quickly before powering his shot into the top left of the Leeds net.

The second half was a calmer affair, with Leeds matching Liverpool for possession and deservedly levelling through Klich's fine strike until striker Rodrigo, making his debut, mistimed his challenge to concede a needless penalty that Salah was never going to miss.

Salah acknowledged the part the opponent had played in a pulsating start to the new season.

"Leeds are a tough team. They had a great game and reacted really well," he told Sky Sports.

"I'm happy about the result and we have to keep on improving. It's important for me to stay focused. We had a good game."

Klopp summed up the thoughts of many after a memorable clash.

"What a game. Football as it's best. What a spectacle," the Red boss said.
