I'm sure the coach is aware of the situation, and we will see a big rotation from the squad in next league game ahead of the UCL Semi final.
I think so, there is very small chance for Atletico to take the first position with 4 matches left. Mathematically Barcelona needs 4 more points to lock the title and I think it can be done by the next two matches even with non full team squad. I dont mean to underestimate Levante and Celta Vigo, but it is a fact that both team are still considered as low team.
