When national team coach Didier Deschamps announced his decision to leave Manchester Citys Samir Nasri out of his 23-man FIFA World Cup squadnot even handing him a place on the seven-man reserve list per ESPN FCthe reaction outside of France was one of incredulousness.Inside, however, the non-selection of the 26-year-old was not greeted with surprise as it had been expected. Why did Nasris omission from the final 23-man squad not provoke an outcry in his home country then'Simple. The talented Frenchman is not the same player for Les Bleus that he is for his club. On top of that, Nasri is seen as a disruptive character and has a chequered history when representing the national team per ESPN FC.As Deschamps also revealedagain per ESPN FCthe Manchester City man finds it difficult to accept that he is not a key part of this France side because of his inconsistent performances. The 45-year-old evidently did not feel that he would play a major role in Brazilespecially since changing to a 4-3-3 formationso opted to leave him behind instead.The former Olympique de Marseille coach is prepared to live or die by his decision, but he could be made to regret it later this summer.With Nasriwhen he is in formyou have a tremendously creative talent, and that is something that this current French team is in short supply of when you consider the struggles that Bayern Munichs Franck Ribery and Real Madrids Karim Benzema have gone through on the international stage.Looking at the current 23-man squad, you can see why Deschamps felt as if he could leave Nasri out.There is still an abundance of potential creative talent with the likes of Ribery, Benzema, Nasris former Marseille teammate Mathieu Valbuena, Juventus Paul Pogba, Paris Saint-Germains Yohan Cabaye and Real Sociedads Antoine Griezmann.However, the problem for the French is that their star players productivity at club level is rarely replicated at international level, and because of this, it is a lottery as to who will actually perform when the tournament starts.With Nasri in the squad, Deschamps would have had one extra and potentially game-changing option to toy with.The 4-2-3-1 formation that France were playing prior to their 3-0 second leg play-off victory over Ukrainea system that suited Nasris positioning perfectlywas dispensed with after the disastrous 2-0 first leg defeat in Kiev. The Manchester City man was guilty of putting in a torrid performance, knowing that it was one of his last chances to impress his coach.His inept showing suggested thateven in his favoured positionit is not certain that he will put on a display that reflects the best of his abilities. Nasris underperformance in Kiev badly damaged Deschamps confidence in the player, and partly as a result, the coach opted to change to a 4-3-3 system instead.Although that style does not suit Nasri, he still could have contributed from there for Les Bleus in Brazil.Thanks to a lack of right-sided options, had the former Arsenal man featured in South America, he would likely have been deployed on the right of the front three. Benzema occupies the central role, with Ribery on the left and one of Valbuena, Griezmann and possibly even Newcastle Uniteds Loic Remy on the right.Also, with few options at the point of the attack outside of Benzema and Arsenals Olivier Giroud, Nasri could also have provided valuable flexibility in a supporting role behind the two. Deschamps would have had to show some bravery for that to have happened, though, seemingly reticent to try it otherwise.Nasris unpredictability could also have worked in Les Bleus favour.Already under pressure to perform prior to the Ukraine play-off doubleheader, the creative talent has a point to prove to his country and is running out of chances to do so. The World Cup could have provided the much maligned with the best opportunity for redemption in circumstances that would have forced him to raise his game.However, Nasri wont be at the World Cup this summer and instead will have to make do with watching on from afar.If France fall early on or are sent packing because of a lack of penetration later on in the competition, expect this debate to reignite and for the issue of Nasris omission to become a more pertinent question back home.Read more World Football news on BleacherReport.com Click here to read full news..
