I think that both Kante and Pogba are past their peak years when they were really influential in the French team. Someone who also fitted that acclaim was Dimitri Payet who was a really creative and dynamic midfielder. A lot of French fans cannot understand why he was not selected this time after missing the 2018 World Cup due to an injury. Yes Benzema is a huge miss also for France. Another player that could have brought some flair to the French team is Newcastle's Saint-Maxim. He has been in astonishing form for them. Well shows that maybe France has a very deep squad and to me are the favourites to retain the trophy.
I thought exactly what you said about Pogba and Kante on Griezmann. He was poor from June to September in the 6 matches(1 win, 3 draws and 2 losses) that France played in the Nations league. However, I was terribly wrong as he is possibly their best player along with Mbappe in this world cup.
I'm not sure why/when Deschamps stopped selecting Payet. I might be wrong but I don't think that he has played for France since the Euro 2016 tournament.
His selection was also highly criticized by the French media mainly the fact that he brought 6 central defenders and didn't bring enough natural wing backs like Mendy(R. Madrid), Digne(A.villa) and Clauss(Marseille). Another criticism happened when he chose to bring Kolo Muani as replacement for Nkunku instead of Fekir who was part of the winning group in 2018 and has a more similar style of play.
He was asked yesterday if Benzema would play or be present as a guest. His answer was "I think your question lacks tactfulness, we had a injuries before the beginning of this tournament and from that moment my squad number was reduced to 24. The team that I will select for the final will be from that group. I don't know if Benzema will be present as I am not the one in charge of sending the invitations"
Yes France has a lot of squad depth when everyone is fit but I don't think this is the case now. They did rotate their squad for their last group match against Tunisia(0-1 loss) and they played both Camavinga (left back) and Guendouzi (left forward) out of their normal position. Regardless of what happened, I think France performance is already a success given the players that couldn't make it.
I think we will have 2-3 goals in this final as both teams got a lot of firepower upfront. I just hope that we will get a winner by the end of the 90 or 120 minutes as I am not a fan of deciding the winner on penalty kicks. The only thing that we know for sure is that at the end of tomorrow, we will have a country who has won the world cup for the 3rd time.
