Messi subbed off for Iniesta could also work considering that Rafinha-Rakitic or Xavi-Rafinha is probably going to be the CM pairing.
Rakitic should probably play the next match.
A player from the first 11 shouldn't be benched for 2 matches in a row. (Imagine benching Neymar for 2 matches in a row.)
So, it should be either Rakitic-Rafinha, Rakitic-Iniesta or Rakitic-Xavi in the next match.
Anyway, our fixtures are now:
1. Home Levante, 15-02
2. Home Malaga, 21-02
3. Away Man. City, 24-02
4. Away Granada, 28-02
5. Away Villareal, 04-03
6. Home Rayo, 08-03
7. Away Eibar, 14-03
8. Home Man. City, 18-03
9. Home Real, 22-03
-- now, Lucho should do some maths
-- for example, we play at home with Levante, and then we have 6 days without matches
= so no need for 3-4-5 rotations (like when we were going to Christmas break or before international break)
-- Levante is poor, but we don't have matches for 6 days, so no need to play too many new players
-- again, if Rakitic was rested yesterday, there is no reason to rest him again, he will have 14 days without full matches then
-- also, if Busi was rested, he needs to play now, because again, he will have 14 days without matches then
-- in the 3rd match, against City, we will play with our first 11, so, in a match against Malaga at home, we can rotate 1-2 players, but not Msn trio and not more than 1 midfielder, because Malaga isn't a weak opponent
-- in the 4th match, against Granada away, we can make 2-3 rotations, but again, never TOO MUCH, we need 3 points in all matches
Anyway, my point is that we shouldn't rotate too many players against Levante, because we have 6 days of break after that.
Pedro for Ney, maybe Bartra for Pique, and either Busi-Rakitic-Iniesta or Busi-Rakitic-Rafinha, because Busi and Rakitic didn't play yesterday.
