Though I understand you made a mistake with your choice of word pertaining the club you intended to write about, but I think I should correct you. Inter Milan isn't playing in the UEFA Europa League competition rather it is AC Milan that will be playing in the playoff Europa League after finishing third in the group F in the just concluded group stage of the UEFA champions league so I believe you meant to write about AC Milan and not their city neighbours Inter Milan.
Again, Atletico Madrid finished as the group winners of the group E in the UEFA Champions League and wouldn't be playing in the Europa League.
AC Milan who play Stade Rennais in the playoffs is one of the strongest teams of the competition and it's believed that they're surely gonna reach the round of 16 because their superior number of quality players. But if they should progress and meet either of Bayer Leverkusen and Liverpool, they might be ousted from the competition by either of the two teams.
They’re a team that’s quite determined and have a good experience on European football. But the issue os that they might possibly shy out when they meet with the big boys of the competition amd that’s one thing they need to work on before resumption of the competition in February. They need to fix up their injury issues so as to build a formidable squad to challenge for the Europa League else they’ll not be going far in that competition.
I do not understand the tactics of the coach lately, they the management have just decided on their own to leave him for a while tnays what I'm guessing..... He's been sent down from the Champions League to Europa League Competition and in the Scudetto Competition, he's also not doing very well like he did the season he wom them the Seria A.
I'm sure Ac Milan would still go through from this very tough round of sixteen. They're big European giants, I don't think they'll want to miss and joke with this one. Having a Liverpool versus Ac Milan in the Europa League Competition finals would make lots of sense, I'd want to see that rivalry once again.
