There have been excellent draws today and I believe that the most interesting games of these round of 16 are
Rome vs brighton
Sporting vs Atalanta
Marseille vs Vilillaal
Freiburg vs West Ham
For me they are the games to be kept more but the others are also quite interesting
There are no doubts now things are going to be interesting as we have top 16 teams in this round and these matches are going to have something special while Roma will host Brighton and Sporting going to face spirited Atlanta Marseille which done good job against Shakhtar now having another challenge as they will host Villarreal which is struggling but can bring good performance in this match and Freiburg which eliminate Lens now have to face West Ham which is currently at worst level with no win into Premier League for last few games, but surely they can do good in this event and have good chance of win as well.
For me most chances Roma, Atlanta, Marseille and West Ham these will be gone into next round because these are having good experience and good performance into their last games and with the same level they can jump into round of 8.
For Roma it will be a very challenging match, Brighton play very attacking football and are often very difficult to beat, while Roma are often very inconsistent in their performances. They will be two very interesting challenges to watch
