The Algeria Football Federation (FAF) has called for a replay of their World Cup play-off clash against Cameroon and lodged a complaint to FIFA over the refereeing, claiming the officiating "distorted the result".

Karl Toko Ekambi delivered the decisive strike in the 124th minute in Blida on Tuesday to condemn Algeria to a 2-1 aggregate loss on away goals, with Cameroon qualifying for Qatar 2022.

Islam Slimani saw two goals ruled out, the first in the second half and again in extra time, with referee Bakary Gassama initially allowing the latter finish to stand before using the pitch-side monitor to deem the Algeria striker had handled the ball.

Charaf-Eddine Amara has resigned as president of FAF left in the wake of Algeria's exit from World Cup qualifying, while the federation has lodged an appeal to world governing body FIFA.

"The Algerian Football Federation (FAF) has lodged an appeal with the International Federation of Association Football (FIFA) against the scandalous arbitration which distorted the result of the Algeria-Cameroon play-off," the statement read.

"The FAF is determined to use all legally permitted means to have its rights restored and to replay the match under conditions guaranteeing the honesty and partiality of the arbitration.

"The FAF also requests the opening of an investigation by FIFA bodies to shed light on the arbitration of the Algeria-Cameroon match."

The draw for the group stage of the World Cup is set to take place on Friday.

Sadio Mane is proud to have helped Senegal overcome Egypt and qualify for the World Cup and says he was "luckier" to get the better of Liverpool team-mate Mohamed Salah.

Senegal beat Egypt on penalties in Tuesday's qualifying play-off in Dakar after winning 1-0 on the day to level the tie at 1-1 on aggregate.

Mane sunk the decisive spot-kick in a shoot-out overshadowed by the Egypt players – including Salah, who missed the opening kick – being targeted by lasers from the stands.

Senegal's triumph comes seven weeks on from beating the same opponents – again on penalties – in the Africa Cup of Nations final.

While happy at getting the better of Liverpool colleague Salah, Mane accepts the outcome of both games could have been a lot different.

"I won twice and he lost twice. I was luckier to come out on top," Mane told OnTime Sports.

"I am very proud that we won the Africa Cup of Nations and now qualified for the World Cup, it's a dream I had.

"It was a difficult game for both teams. Our fans pushed us to win and we didn't stop fighting. We knew the game wouldn't be easy but we pressed to score."

Senegal join Ghana, Tunisia, Morocco and Cameroon as Africa's representatives at Qatar 2022, with Nigeria, Mali, DR Congo and Algeria falling at the final hurdle.

Mane and Salah could reunite on the pitch next weekend, meanwhile, when Liverpool return to Premier League action against Watford.

Virgil van Dijk has backed Liverpool team-mate Mohamed Salah to "turn disappointment into success" after Egypt failed to qualify for this year's World Cup.

Salah, who had lasers directed at him from the crowd as he lined up his spot-kick, blazed over in the penalty shoot-out on Tuesday as it was Senegal – spearheaded by fellow Liverpool star Sadio Mane – who booked their spot in Qatar following a 1-1 aggregate draw across two legs.

It was the second time this year that Salah and Egypt have suffered shoot-out agony against Senegal, who triumphed in the same way in the Africa Cup of Nations final.

Salah has been one of the standout players in European football this season, yet will not get the chance to show his quality on the biggest international stage.

While Van Dijk is disappointed for Liverpool's talisman, he is confident the forward will use Egypt's failure to spur the Reds on to more success this season, with a quadruple still on the cards for Jurgen Klopp's team.

"Well obviously, I feel sorry for Mo and for Egypt, but football is sometimes like this," Van Dijk told reporters after featuring in the Netherlands' 1-1 friendly draw with Germany.

"I am sure he will turn the disappointment into success for the rest of the season.

"We still have everything to play for so there is a lot of things still to achieve for him."

While Salah will return to Liverpool disappointed, Mane will come back knowing he is set to lead Senegal, who exited in the group stage in Russia in 2018.

Van Dijk was thrilled for Mane, but could not resist firing a warning shot his team-mate's way.

"As for Sadio, I wish him all the best and if he is in our group, he is going to need that good luck," the defender added.

Egypt complained they suffered a bus attack and alleged Mohamed Salah faced racist abuse before their chaotic World Cup play-off defeat in Senegal.

The protest came before kick-off at Stade Abdoulaye Wade, where Senegal avenged a 1-0 first-leg defeat with victory by the same margin, before winning a controversial penalty shoot-out.

When it came down to spot-kicks, Egypt's players had lasers pointed towards them by home fans, a likely distraction as three visiting players, including Liverpool's Mohamed Salah, failed to convert.

That allowed Senegal to win 3-1 in the shoot-out, with Salah's club-mate Sadio Mane netting the winning strike.

It had been a challenging day for Egypt even before the game began, with pictures posted by their national football association indicating the team bus had been struck by missiles on its way to the stadium, which is situated a short distance outside Dakar.

One window was shattered, while evidence posted on social media by Egyptian authorities showed an apparently cracked windscreen and a rock that had been thrown into the vehicle.

The Egyptian FA (EFA) also posted a picture from inside the stadium of a banner reading "F*** YOU SALAH".

The EFA said in a statement: "Egypt files an official complaint against Senegal due to the attack and the racist banners.

"The Egyptian team was subjected to racism after offensive banners appeared in the stadium stands for the players, specifically Mohamed Salah, the team leader. This was documented with pictures and videos that were attached to the complaint."

Egyptian media said the complaint had been filed to CAF – the African confederation – and world governing body FIFA.

Furious Nigeria supporters stormed the pitch at the National Stadium in Lagos after rivals Ghana sealed a World Cup spot at the expense of the Super Eagles.

Arsenal's Thomas Partey opened the scoring in the 10th minute for Ghana, before William Troost-Ekong levelled from the penalty spot for the hosts midway through the first half.

Nigeria could not find a crucial second goal, however, with Otto Addo's Ghana side holding on for the 1-1 draw, to progress to Qatar 2022 via away goals after a 0-0 draw in the first leg.

The result sparked ugly scenes inside the stadium, with videos on social media showing supporters leaving their seats and smashing equipment at the side of the pitch.

There was heartbreak for Mohamed Salah and Egypt after they suffered another dramatic penalty shoot-out defeat to Senegal.

Hosts Senegan recovered from a 1-0 first-leg deficit to beat Egypt by the same margin at the Abdoulaye Wade Stadium, before Salah, with dozens of laser pens seemingly pointing at his face, fired Egypt's first penalty of the shoot-out over the bar.

Mostafa Mohamed later failed with the visitors' fourth kick, allowing Salah’s Liverpool team-mate Sadio Mane to slam his penalty past Mohamed El Shenawy and seal Senegal's progress, in a repeat of February's Africa Cup of Nations final triumph.

"We try our best but today was not enough," he wrote. "To all my players and my staff, [I give] my recognition and humble thank you.

"You will be always in my heart. It was my privilege to work and be helped by such dedicated and capable professionals and wonderful friends."

There was stunning late drama in Bilda as Karl Toko Ekambi scored late in extra time to seal a 2-1 win for visitors Cameroon against Algeria, the Indomitable Lions progressing to Qatar via away goals after a 2-2 aggregate draw.

Algeria thought they had sealed a place at the World Cup when Ahmed Touba cancelled out Eric Maxim Choupo-Moting's opener with two minutes remaining in extra time, but there was just enough time left for Ekambi to seal the most dramatic of victories.

Morocco also booked their place in Friday's World Cup draw with an emphatic 4-1 win over Democratic Republic of Congo. A brace from Azzedine Ounahi, as well as goals from Tarik Tissoudali and Achraf Hakimi, sealed a 5-2 aggregate win over DR Congo, who scored a late consolation through Ben Malango.

Meanwhile, a 0-0 draw for Tunisia against Mali was enough to see the former seal their own place in Qatar after they managed a 1-0 win in the first leg.

Sadio Mane fired Senegal to the World Cup as Liverpool team-mate Mohamed Salah suffered penalty shoot-out agony with Egypt after being targeted with lasers by fans.

Senegal recovered from a 1-0 first-leg deficit to land victory by the same margin at the Abdoulaye Wade Stadium on Tuesday.

That meant the play-off, tied at 1-1 after 120 minutes of the second leg, went down to a battle of spot-kicks to decide who would go to Qatar 2022, and Salah missed Egypt's first penalty when he fired over the bar.

Lasers flashed across the pitch and were directed at Egypt's star man, who could not find the focus to convert from 12 yards.

The first four penalties were missed, with Salah's the second of those, before both sides netted their third kicks.

Egypt's Mostafa Mohamed failed with the visitors' fourth penalty, seeing his shot blocked, and that allowed Mane to step up and crack a fierce spot-kick past Mohamed El Shenawy, booking a place in Friday's draw.

Will it be Mohamed Salah or Sadio Mane? Italy or Portugal – or indeed neither? Can Canada end their long wait, and are the United States and Australia at risk of missing out?

Those questions and plenty more are set to be answered over the next week or so as World Cup qualifying concludes for many nations.

Just 15 of the 32 participants have so far been confirmed for Qatar 2022, leaving 48 teams battling for the 17 remaining spots.

Fourteen more countries will be assured of a finals berth come the end of next week in what is very much crunch time for those still in contention.

Stats Perform looks at the key talking points.

Egypt seeking revenge in AFCON final repeat

Less than two months on from meeting in the Africa Cup of Nations final, Egypt and Senegal face off over two legs for a place in Qatar.

Senegal prevailed in a penalty shoot-out to claim their first AFCON crown and, buoyed by that triumph, will consider themselves as favourites here.

While both teams boast an array of top-class talent, this fixture is being billed as a showdown between Liverpool team-mates Salah and Mane.

The two biggest stars in African football, only one of the pair will be part of the World Cup later this year – and neither will fancy watching it all unfold from home.

This is not the only grudge match taking place in the CAF section over the next week and a half, as fierce rivals Ghana and Nigeria will also face off in a two-legged play-off.

Cameroon are up against Algeria, Mali take on Tunisia and DR Congo meet Morocco in the other three ties, each of which will be concluded on March 29.

European heavyweights on collision course

Since the play-off draw in the UEFA section took place in November, all talk has centered around a potential meeting between Italy and Portugal for a place in the finals.

The winners of the past two European Championships, either the Azzurri or the Selecao will miss out on the biggest tournament of them all.

It should never have been this way, of course, as both teams were strong favourites to finish top of their groups and qualify automatically.

Italy finished second to Switzerland and Portugal were runners-up to Serbia, meaning the sides must now come through two qualifying ties.

First up for the reigning European champions is a meeting with North Macedonia in Palermo, while Portugal face Turkey in Porto, with the winners of both ties advancing.

Should, as expected, Italy and Portugal come through those semi-finals, the latter will have the advantage of staging the final on home soil five days later.

For Portugal skipper Cristiano Ronaldo, it presents what will surely be his last chance to play at a record-equalling fifth World Cup.

Pathways impacted by political events

Path C of UEFA qualifying is undoubtedly the most eye-catching, but there are also some tasty fixtures in the other two sections – not least a possible Home Nations derby.

Scotland and Wales were kept apart in the Path B semi-finals but could meet in the final should they overcome Ukraine and Austria respectively.

However, due to ongoing events in Ukraine, their game against Scotland has been pushed back – likely until June – as has the final involving either Wales or Austria.

In Path C, Russia had been due to face Poland, but the invasion of Ukraine forced FIFA and UEFA's hand and they have been banned from competing.

Poland have therefore been handed a bye to the qualifying play-off final, where either Sweden or the Czech Republic await. That match will be contested next week as planned.

Canada on verge of ending long wait, USA with work to do

The United States qualified for every World Cup between 1990 and 2014, but they missed out on a place at Russia 2018 after an embarrassing loss to Trinidad and Tobago.

Gregg Berhalter's side are by no means assured of one of the three automatic qualification spots in the CONCACAF section this time around, either.

USA sit second with three games to go, but they still have to travel to third-placed Mexico, as well as facing Panama and Costa Rica, who occupy fourth and fifth respectively.

Level on points with Mexico and four ahead of Costa Rica, it could be a tense finale to qualifying for the Stars and Stripes.

That should not be the case for Canada, who are eight points clear of fourth and are all but assured of ending their 36-year wait to make a second World Cup finals appearance.

Brazil and Argentina through, but who will join them?

The drawn-out South American qualifiers are nearing their conclusion and only four of the 10 sides know their fate at this juncture.

It has been plain sailing for Brazil and Argentina, who are assured of an automatic qualifying spot with three games to go, including a rescheduled meeting between the pair.

Behind those perennial World Cup representatives are Ecuador, who have been the surprise package in qualifying and can finish no lower than fifth.

Ecuador will not be content with anything other than a top-four finish, though, and they can make certain of that with victory over Paraguay.

Assuming Ecuador get over the line, that will leave Uruguay, Peru, Chile, Colombia and Bolivia battling it out for progression, which sets up some intriguing fixtures.

Uruguay occupy fourth place, meaning their qualifying aspirations are in their own hands, but they have Peru and Chile – the two sides behind them – still to face.

Socceroos sweating on finals spot

Only four teams advance automatically from the CONMEBOL section, with the team in fifth entering a play-off against the winner of the AFC fourth round in a one-off tie in June.

That may well turn out to be Australia as the Socceroos are five and four points behind top two Saudi Arabia and Japan in Group B with two games to go.

However, those remaining two fixtures are against those nations occupying automatic qualification places, so Australia may yet sneak through.

Iran and South Korea have already made certain of progression in Group A, meanwhile, leaving the United Arab Emirates, Lebanon and Iraq to compete for third place.

The two third-placed finishers – which, as it stands, are Australia and the UAE – will meet in a one-legged match ahead of that aforementioned play-off with a CONMEBOL side.

Ajax goalkeeper Andre Onana incredibly walked away without serious injury from a major car crash on his way to join up with the Cameroon national team on Tuesday.

Onana, who is expected to join Inter at the end of the season on a free transfer, was travelling from the capital Yaounde to the port city of Douala, where the Indomitable Lions are gathering ahead of their World Cup play-off against Algeria.

Local media showed pictures of the car in which Onana was travelling, and another vehicle, with the front part of each being badly mangled.

Onana, 25, was taken from the crash site to the Cameroon team base and posed for pictures, appearing unhurt; however, it was determined he should head for hospital check-ups.

"Andre Onana is fine," the team's official Twitter page stated. "The Indomitable Lions goalkeeper joined his team-mates in the den in Douala this morning.

"More fear than harm for the moment after the traffic accident he suffered early this morning in Sombo on the Yaounde to Douala axis.

"Andre Onana will undergo in-depth examinations in a referral hospital centre in Douala."

Cameroon will host Algeria in the first leg of their play-off on Friday, with the second leg taking place in Blida next Tuesday. The aggregate winner will qualify for the Qatar 2022 finals.

The 2022 World Cup gets underway in exactly one year's time.

The tournament has courted controversy ever since its hosting rights were awarded, but it promises to be quite the spectacle in a part of the world that has never hosted it before.

Here is everything you need to know about the finals...

Where is the World Cup being held?

The 2022 World Cup takes place in Qatar. It is the first time the tournament will be held in the Middle East

The finals will be staged in five cities: Al Wakrah, Al Khor, Al Rayyan, Lusail, and the capital, Doha.

Qatar is the smallest country ever to host the World Cup. With a surface area of 11,500 square kilometres, it is the 158th largest country in the world and can be traversed in roughly two hours.

A peninsula nation whose economy is powered by oil and natural gas, Qatar has been constructing what FIFA describes as "some of the most eco-friendly and architecturally advanced sporting facilities ever seen" ahead of the tournament.

When does the tournament take place?

The 2022 World Cup will be held from November 21 until December 18, with 64 matches played. The time frame has been slightly condensed because of the impact a winter World Cup will have on many of the world's domestic seasons.

The opening match takes place at Al Bayt Stadium on November 21, with the group stage finishing on December 2. The round of 16 begins the following day.

The quarter-finals will be held on December 9 and 10, with the semi-finals on December 13 (at Lusail Stadium) and December 14 (at Al Bayt Stadium).

The third-place play-off is on December 17 at Khalifa International Stadium, with the final on December 18 at Lusail Stadium.

What are the venues?

The tournament is being held across five city regions: Al Wakrah, Al Khor and Lusail contain one stadium each, with two in Al Rayyan and a further three in Doha.

The venues and their capacities are:

Al Rayyan
Ahmad Bin Ali Stadium: 44,000

Education City Stadium: 45,350

Al Khor
Al Bayt Stadium: 60,000

Al Wakrah
Al Janoub Stadium: 40,000

Doha
Al Thumama Stadium: 40,000

Ras Abu Aboud Stadium: 40,000

Khalifa International Stadium: 40,000

Lusail
Lusail Iconic Stadium: 80,000

Which teams have qualified?

At the moment, the following teams have qualified for the finals:

Qatar (automatically qualified as host nation)

Denmark

Germany

Brazil

France

Belgium

Croatia

Spain

Serbia

England

Switzerland

Netherlands

Argentina

Why is it controversial?

The bidding process for the hosting rights for the 2018 and 2022 World Cups has been beset by allegations of corruption.

Although a FIFA investigation cleared Qatar of wrongdoing, Swiss federal prosecutors opened criminal proceedings into the awarding of the two tournaments as part of a wider probe into alleged criminal activity concerning some former FIFA executives.

Concerns have also been raised about the treatment of migrant workers used in the massive construction projects for the tournament. Amnesty International said labourers in Qatar were subject to abuse, inhuman working conditions and little pay, describing "a playground for unscrupulous employers" in September 2019.

In response, Qatari authorities changed their employment law after entering a partnership with the UN's International Labour Organisation (ILO) aimed at reforming their labour policies. The introduction of a new minimum wage and a commitment to end the 'kafala' system, which made it impossible for workers to change jobs without their employer's permission, were welcomed by the ILO and Amnesty International.

The decision to stage the World Cup during the Northern Hemisphere's winter was taken due to the extreme heat common in summer in Qatar. However, moving the tournament to November and December, when the European club season is at its busiest, will create a knock-on effect for 2022-23.

The Premier League, for example, plans to take a seven-week break between November 13 and December 26 to accommodate the World Cup, while the Champions League final is set to be pushed back into June. There are concerns about the physical toll the prolonged season will have on players; Aston Villa chief executive Christian Purslow described it as a "crazy idea".
