Based on the calculation of points earned in the domestic league, Barcelona is better than Napoli, but overall, both teams are not at their best. Inter Milan are in top form, they are very obsessed with returning to the final and winning the UCL trophy after failing in the final last season. You also shouldn't underestimate Atletico Madrid, this team just held Real Madrid to a draw in La Liga, Simeone team also embarrassed Real Madrid in the Copa Del Rey with a landslide score of 4-2. Inter are better prepared to advance to the next round judging by their performance, but Atletico will try to knock Inter out quicker with their aggressive displays this season.
Inter Milan will surely show som positive improvement that will make people to believe that they are on their way to lift this UEFA champions league trophy because, they have displayed some improvement in some competition to be in the top in the Italy serie A table to ensure they maintain the position till the end.
If inter Milan can disgraced Juventus that is forming strong team in this season and, it was a surprised game for Inter Milan to secure one goal to beat Juventus 1:0 and they still have that strength to beat Atletico Madrid if they have the opportunity to meet again before the end of the tournament.
Inter Milan is surely team to watch in coming matches with their current performance is surely at the top, and they have enough quality to win against any team with in last few months mostly are talking about Manchester City, Real Madrid and Bayern Munich with these teams no one talking about Inter Milan as they are not near these teams but most chances they are having fair chance for the win and their game against Atlético Madrid is surely going to be tested case which will give all review about them if they are able to win then surely they could be in good position and also have good chance for the win.
Atlético Madrid is also not easy team but their performance i surely not near to beat Inter Milan with their home game can give them some advantage but still for the game which is going to play at Inter Milan home could be not easy for them.
