With the condition of the players who have recovered such as Di Maria, Chiesa, Dusan and even Pogba of course at this time Juventus' condition is much better than before so they will be able to make it possible to successfully advance to the next round in the Europa League.
Juventus' condition is in contrast to Nantes because it seems they are still not ready to be in this league, especially with their not-so-good condition in the Europa League and Ligue 1.
Juventus has rediscovered its best form in Serie A and the Bianconeri have also received good news because several of their players who are currently undergoing treatment for injuries have now recovered. The World Cup break can be a blessing for Juventus because it can be maximized for the player's recovery period.
I'm sure Juventus will go faster in the Europa League, they are strong candidates this season with several teams eliminated from the Champions League. The Play-off match against Nantes is certainly not difficult for the Old Lady, but Allegri must also be wary of the rise of the representative from France. The Europa League playoff schedule will take place in February, so both teams still have time to prepare.
