I think Barcelona will still be on top at the end of the trip. They are playing better by the week, and Atletico is going downwards.
Atletico Madrid just have one difficult match against Barcelona so they have chance to keep it on the top of the table. Even they are facing some problem with their form but Barcelona is also very dangerous at the moment so can ignore them. But my vote will remain with Atletico Madrid.
Barcelona left two big match with Real Madrid and faced with Atletico Madrid, but if success pass and get three points from two match become easy chance to get trophy exactly they only have focus with La Liga after failed to knock out stage on champion league, but for Real Madrid have important match for two weeks later faced with Barcelona and later have ready to fight with Liverpool on champion league.
