The match has ended in the favour of Atletico Madrid and I'm not surprised. Sevilla has nothing going on for them right now. Their form is too bad right now to be a challenge for Atletico Madrid.
I don't know what it is with Atletico Madrid but 2 of their centre-backs got red cards in back to back matches. Atletico Madrid regained their 3rd position with this victory over Barcelona.
This season things continued to get worst for Sevilla and I would have not expect them to get a comeback win, if Atletico Madrid were down to 10 men and this is what we saw today. Atletico Madrid has been in an excellent form this season just unfortunately that Madrid, Barca and Girona as been better while Barca is now losing in the title race and Atletico finally caught up with them and if Girona continues like this then they may finish 3rd or 4th place cause I don't see Real Madrid dropping point.
If Barcelona's performance doesn't develop, they might be even out of the top 4 in the next few game weeks if they doesn’t develop. Their forward needs improvement and the defense needs improvements. I will agree with you, Lewandowski isn't certainly at his best form right now. Probably they could improve their squad in the January transfer market
Let be realistic Barcelona don't have any choice than to stick with what they have and hope Lewandowski will get back to his best quickly or try to not depend on a striker rather any of the players can get a goal because what matters in the end is for a team to win. My reason for this is that Barcelona don't need another under performing players like Ferran Torres and Felix but a player who is consistent like Lautaro Martinez but this they can't get with their current financial crisis and so its better to stick with what they have
