The NPFL: Questions Remain on Game Integrity Inspite of Slight Improvement.....

On July 18 of 2013, I ran some numbers to check on the integrity of the elite league in Nigeria (Click here) and they revealed serious questions regarding integrity of the league. The 2013 data compare the league in Nigeria to those in Ghana, South Africa, and England on percentages of home and away wins. Nigeria's percentages were aberrant compared to the three other leagues. Nigerian home teams won 77% of their matches, an incredibly huge percentage. Moreover, home teams were awarded 100% of the penalty kicks most of which came in the second half. Then 2013 was compared to the Nigerian league of 1979. The difference was stark. The 1979 version was statistically similar to other non-Nigerian leagues. In essence, it demonstrates how decadent the Nigerian league has become since the credible years, several decades ago! 

Seven years after that 2013 blog, I now use the Sofascore website to check on the same issues. The data are accessed March 1, 2020. This time, I compare the Nigerian league with the 1979 and 2013 data (Table 1); against the Top 5 leagues of the world + the Brasileiro (Table 2); and 18 of its counterparts in Africa (Table 3).












The percentages from Nigeria are so off that they raise major questions about the Nigerian league's integrity. However, there is good news. Compared to 2013, there is an improvement. Less home wins and slightly more away wins. Although, the home wins have declined, they have only slightly gone down. They still stick out like a sore thumb when compared with other leagues' home wins.

















Data still demonstrate that Nigeria has 10% points over any of the selected leagues on home wins and over the averages for home wins. Nigeria is also 10% points lower than any other league in away victories and 10% points lower than the averages for away wins. There are a few other aberrations from other leagues as well (see those highlighted in red). 




























Let us be clear. The Nigerian Federation recognizes this problem in a statement made by its then Secretary General, Fanny Amun, back in 2006 and I quote:

         We know match officials are offered money or anything to influence matches 
          and they can accept it. . . Referees should only pretend to fall for the bait, 
          but make sure the result doesn't favor those offering the bribe.

It was a shocking statement by someone in authority in Nigerian football and it was widely reported across the world. But acknowledging bribery has a benefit -- it is a realization of a problem. Of course, one cannot like the fact that he encourages the match officials to accept bribes as part of a solution. Nevertheless, the revelation from such a high office means that the Federation realizes the lack of integrity of match results in its elite league. 

Obviously, the Federation is improving in terms of erasing the "win-at-home-at-all-cost" strategy that appears syndicated via match officials.  The fact that all other leagues fall within 10% points of both averages for home and away wins and that Nigeria's elite league of 1979 also fell within those margins indicate what league result normality should be in statistical terms. Falling far away from that normality, in spite of improvement, underlines the fact that more work is still required.

Lookman with a Brace as Nigeria Overcomes Cameroon 2-0......

Image
Abidjan -- Nigeria moved into the African Football Cup of Nations (AFCON) quarter finals with Ademola Lookman scoring a brace in a 2 - 0 win over Cameroon. Nigeria played a clinical game and remained focused allowing Cameroon to dominate possession but offered the losers few real opportunities. Desperate to measure up, Cameroon made Osimhen suffer several fouls and the increasing desperation led to a caution for Nkoulou who fouled goalie Nwabali in midair. Nwabali, unable to continue, was replaced by goalie Uzoho. _____________________________________________________ Desperate to measure up, Cameroon made Osimhen suffer several fouls and the increasing desperation led to a caution for Nkoulou who fouled goalie Nwabali in midair.

Nigeria Scraps Through Deservedly....

Image
Abidjan -- Nigeria pipped Guinea Bissau 1-0 in Abidjan at the Houmphouet Boigny Stadium to progress to the second round of the AFCON before an estimated 20,000 spectators. With Ivory Coast going down 0-4 simultaneously to Equatorial Guinea, Nigeria was forced to finish second in the group because of a poorer goal difference compared to the Equatoguineans. Nigeria was clearly the better team using their new structure of 5-3-2 in defense and 3-5-2 in attack. In truth, the losers, who finished without a point in the group, were thoroughly outclassed. The difference in margin could be down to pitiful officiating by referee Ms. Bouchra Karboubi (Morocco) intent on balancing the game with poor officiating. Although, to be clear the referee with assistance of VAR officials ended up making the correct calls after Nigeria had put the ball in the net two other times and fortuitously did not call for a VAR check after the losers had a goal ruled off. Replays indicated the goal by Guinea Bissau sh...

Junior and Simy Needing Prayers and Minutes

We now have a very good idea who Manager Gernot Rohr plans to take to Russia for the 2018 World Cup, barring injury. His decision to name 30 players for the World Cup camp has done little to disguise his final list. In reality, the only unknown is injury and Rohr's decision at just two positions. Rohr's tendencies, from his first day of appointment in Nigeria, is to be conservative and that has increased the predictability of Nigeria's final squad to Russia. Only Two Spots Still Open It is quite clear that 21 of the invited 30 players are already on Rohr's final list to Russia. The nine left are the likes of Dele Ajiboye, Stephen Eze, Ola Aina, Elderson Echiejile, Uche Agbo, Mikel Agu, John Ogu, Simy Nwankwo, and Junior Lokosa. It is among those that the final cut of seven players will come. But even then, we already know the five that are on the list of certain cuts. Those five are Dele Ajiboye, Stephen Eze, Uche Agbo, Mikel Agu, and Junior Lokosa. Of that list,...
