Morocco being awarded the Africa Cup of Nations title after governing body judges overturned Senegal’s victory two months after the chaotic final stunned soccer fans worldwide.

While Moroccans took to the streets to celebrate their team’s belated success, the decision by the Confederation of African Football (CAF) was met with disbelief in Senegal with fans and authorities calling the decision “unjust”. Senegal’s government on Wednesday said it will pursue “all appropriate legal avenues” to overturn the decision and called for an international investigation into “suspected corruption” within African soccer’s governing body.

CAF’s appeals board on Tuesday ruled that Senegal forfeited the final by leaving the field of play without the referee’s authorisation, and it awarded Morocco a default 3-0 win.

Morocco and Senegal have long shared close ties built on religion, trade and culture. Tijaniyyah, a Sufi Muslim order, is widely followed in both countries. Moroccan banks and companies heavily invest in Senegal’s finance and agriculture sectors. Cultural exchanges include student programs, migration and joint festivals.

But the tensions surrounding the final and CAF’s appeals court decision to overturn Senegal’s victory have put a strain on the relationship between the two countries. Last month, 19 Senegal fans who were arrested on charges of hooliganism at the final were given prison terms of up to a year by a Moroccan court. The Senegalese government has expressed solidarity with the Senegalese supporters.

Seydina Issa Laye Diop, president of the Senegalese national team’s fan group called “12th Gaindé” said the incidents should not damage the relationship between Senegal and Morocco. “However, there are limits. If this continues, it could somewhat affect the pride of the Senegalese people,” Diop said.

“If the goal is to preserve friendship, then it must be nurtured. Small gestures can have a big impact. These are things we can move past, especially since, during the trial, no solid argument has justified the continued detention of these supporters.” Mariama Ndeye, a student in Senegal’s capital Dakar, said the decision has negatively impacted her view of Moroccans. “When everything goes well, they call us their brothers. But when things don’t go their way, they start being nasty,” Ndeye said.

On Wednesday, Morocco’s embassy in Dakar called on Moroccans in Senegal to “demonstrate restraint, vigilance and a sense of responsibility.” “It is important to recall that, in all circumstances, it is only a match, the outcome of which should never justify any form of escalation or excessive remarks between brotherly peoples,” the embassy said.

In Casablanca, home appliances business owner Ismail Fnani said he felt like other African countries were rooting against Morocco during the final. “Honestly, my views towards Senegalese and sub-Saharan Africans changed after this,” he said. “We used to feel sympathy and help them because they were migrants who had struggled to get here. Where there was once sympathy and compassion, now I will treat them as they have treated us.”

Senegal alleges favouritism in CAF

The Senegalese government’s allegation of “suspected corruption” at CAF followed anger at perceived favouritism toward Morocco, which is a 2030 World Cup co-host and has invested heavily to become a soccer superpower.

CAF president Patrice Motsepe, however, defended the body against perceptions of favouritism toward Morocco. “Not a single country in Africa will be treated in a manner that is more preferential, or more advantageous, or more favorable than any other country on the African continent,” he said.
