You are right, Inter dominated attacks from the first half even though they failed to score. Atletico Madrid haven't had many goal chances so far, but they are very likely to score and take their chances. So far both teams have found it difficult to score goals because their defense is good, so the possibility of a draw seems to be increasing.
The tension in this match is so high that it is still very difficult to get one of the two teams to score. Good defense is the advantage of both teams, but Inter tends to have a higher chance of winning. Let's wait and see whether Inter can really take advantage of their home advantage or whether Atletico Madrid will win this match.
Inter Milan game in this match was quite good but Atletico madrid had a strong defense so that many of Inter milan attacks did not result in goals in the first half. In the second half Inter milan also still dominated possession of the ball and they continued to pressure Atletico madrid to score goals. These two team have quite strong quality player, but in the first leg of the match, Inter milan was the host, of course Atletico madrid played quite carefully in this match because Inter milan was able to control the flow of the match from the first half.
Thuram has made 2 shots so far. I hope he can make a big contribution to scoring goal in the remaining minutes of the second half. I was impressed with his performance in this match, but yes, Thuram was guarded quite tightly by the Atletico madrid players so it was very difficult for him to find a gap to score. Martinez was the same, he performed well from the first half but unfortunately he failed to convert several opportunities into goals.
