There is a postponed match between Atletico Madrid vs Sevilla today, yes it's a match that should have happened in week 4. I can't count on Sevilla in this match, because this season they are very worrying, in La Liga they are struggling to rise and in the Champions League they have to go home early without even winning 1 victory.
It looks like Atletico Madrid will be able to comfortably win this match, and they can restore their last 2 matches that ended without a win. Sevilla is a very good opportunity for Atletico Madrid to win, especially this is a match that will be held at their own headquarters.
The match has started already and it's in the 20mins with both team playing 0-0. Just like you have said, Atletico Madrid should secure a win here as they are playing with a weaker team.
The match was really a tough one for the both side because there first half was very difficult for Atletico Madrid because it seems that Sevilla really understand the pattern of Atletico Madrid so they had to make sure that Atletico Madrid never get the chance to penetrate there defense line and also what helped Atletico Madrid was there home advantage.
Actually I was thinking at the beginning of the match that Atletico Madrid may likely score on the first half because there performance was quite impressive than Sevilla although I'm not disputing the fact that Sevilla did not perform well because irrespective of Atletico Madrid wining, Sevilla also played very well because if you check there possessions the difference is not much and also at the ending of the match Sevilla was putting more pressure on Atletico Madrid, although Atletico Madrid was very lucky to have scored before there red card because playing with short one is very difficult for a team, so perhaps if they had gotten the red card at the beginning of the match Sevilla would have utilize the opportunity and win them.
I even don't remember the last season in which Sevilla had a good performance and got good results because, in most of the time, they had weak performances in the La Liga and failed in this league.
In the game between Sevilla and Atletico Madrid, they were about to get one point in this match but Marcos Llorente scored a goal and used the chance he had. However, I think the main reason for Atletico Madrid to win this match was the huge mistake from Sergio Ramos the experienced defender of Sevilla.
