Liverpool manager Jurgen Klopp said Alisson’s horrendous error “was clearly going to happen one day”, after his side maintained their 100% start to the season with victory at Leicester.

Klopp’s team looked on course for a comfortable win when, after Mo Salah had uncharacteristically missed an open goal, Sadio Mane pounced in the penalty area to poke Liverpool in front after only 10 minutes.

Liverpool’s position looked even more secure when Roberto Firmino stole in on James Milner’s corner to double their advantage with a header on the stroke of half-time – but they then proceeded to make life difficult for themselves.

And the main culprit was Alisson, the £67m summer signing from Roma, who was embarrassed as he gifted Leicester a goal after 63 minutes when he was robbed by Kelechi Iheanacho while inexplicably performing an elaborate turn with the ball at his feet in the area, Rachid Ghezzal scoring following the ensuing chaos.

Leicester pushed for the equaliser but Liverpool closed out victory to make it four wins out of four at the start of a league season for the first time in 28 years – and leave keeper Alisson the most relieved man inside the King Power Stadium.

“It was clearly going to happen one day,” Klopp said of Alisson’s error. “I didn’t think it was going to happen in the next match [after his successful showboating against Brighton last time out, when he chipped an on-rushing attacker]. It’s all OK. He knows he could have cleared the situation.

“I said last week we need to get used to it. Don’t constantly give the goalkeeper the ball, there are other solutions. He’s a fantastic goalkeeper who makes fantastic saves and of course in this situation he did not do what he should have done, but it’s all good.”

Alisson has already raised eyebrows and attracted attention for his confidence with the ball at his feet, notably his willingness to audaciously chip an oncoming Brighton attacker during last weekend’s victory at Anfield.

There is, however, a time and a place – and the time he chose at the King Power Stadium was definitely not it.

Alisson was trying to be too clever by half when he embarked on a dainty turn and backheel as Iheanacho chased down Van Dijk’s slightly wayward back pass.

For all the modern thinking, this was an occasion when the big boot should have been applied – as manager Klopp’s emphatic gesture on the touchline subsequently suggested. Alisson decided otherwise, played himself straight into trouble and the whole calamity ended with Ghezzal scoring. It gave Leicester the sort of opportunity that could have proved very costly.

Liverpool have suffered enough at the hands of goalkeeping errors, such as those of Loris Karius in the Champions League final, so this moment will have revived some uncomfortable memories.

Liverpool spared Alisson’s blushes by holding on for the three points but you suspect the Brazilian will be on the receiving end of a sharp reminder from manager Klopp not to repeat those sorts of mistakes.

Alisson himself insisted afterwards that he will not make the same error again, describing it as a “reading the play mistake”.

“I didn’t receive that good of a pass, we talked about that in the locker room, I spoke to Virgil, it wasn’t that good of a pass,” he added.

“Everyone analyses the games. Obviously, I won’t be stupid to make the same mistake.

“It’s part of my game, I wont’ be arrogant of saying that I will keep doing this. We have to learn from our mistakes.

“I think that it was a foul, but we can’t support ourselves on that. In this kind of play, here in the Premier League, not every collision is a foul. In my opinion it was, but it’s part of the game, we can’t give room for that to happen on the pitch.”

Leicester show real fighting spirit

Leicester, having kept faith with manager Claude Puel, have made a promising start to the season with victories at home to Wolves and at Southampton following an opening day defeat at Manchester United.

And here, despite the home defeat, there was plenty for Puel and players to take from a display that showed real character and determination, especially without suspended main striker Jamie Vardy.

The Foxes could have been forgiven for thinking the fates were against them when Firmino made that crucial intervention to give Liverpool a two-goal lead right on half-time.

Leicester, however, regrouped and gave it a real go after the break in the sort of manner that suggests more good things than bad lie ahead of them this season, which was reflected in the generous reception their supporters gave them at the final whistle.

Man of the match – Joe Gomez

‘We were a little lucky, but we deserved to win’ – what they said

Liverpool manager Jurgen Klopp speaking to Sky Sports: “We could have scored earlier in the game, I said a few times in the past a dry pitch means not good football. Leicester wanted to be aggressive but couldn’t because we moved so well. We were in a few situations a little lucky, but think we deserved to win.”

Leicester manager Claude Puel speaking to Sky Sports: “I’m disappointed for my players because they gave their best. The second half was fantastic, we showed good quality and had a lot of chances. We had good tempo, good aggression. We played with confidence and we had the chances to come back. It is encouraging.”

Mane loves facing the Foxes – the key stats

Sadio Mane has had a hand in four goals in his last four league games against Leicester (two goals, two assists).

Liverpool have not lost an away league game when scoring first since December 2016, when they were beaten 4-3 by Bournemouth.

James Milner has now registered 80 Premier League assists, the same number as David Beckham. Only six players have more in the competition.

No player has assisted Liverpool’s Roberto Firmino more times in the Premier League than James Milner (8).

Under Jurgen Klopp, Roberto Firmino has been directly involved in 60 Premier League goals (37 goals, 23 assists), 15 more than any other Liverpool player.

Following Rachid Ghezzal’s strike, Leicester became the first Premier League team to have three different Algerians score for them (also Riyad Mahrez and Islam Slimani).

Since the start of last season, no player has more assists in the top four tiers than James Maddison (16). The former Norwich man is level with Kevin De Bruyne and Barry Douglas.

Leicester have lost their last 11 Premier League matches against sides starting the day top of the table, scoring just five goals while conceding 27 in those matches.

What’s next?

Next up for Liverpool is a trip to Wembley to play Tottenham in Saturday’s early game (12:30 BST), while Leicester face Bournemouth at the Vitality Stadium later that day (15:00 BST).
