Rotation will be key, an insane number of games till the end of the season and for sure Pep will have to rotate. The problem with that is the performances will drop when some key player are not in the team sheet. Having Delph against Swansea almost cost us the qualification. Not sure what Marehz is up to theses days as well, very poor.Our April fixture schedule is absolutely insane! If we make it to the end of the month still in the FA Cup and CL, and still in the title race we'll be doing very well. I think Guardiola will try to rotate a little, because he'll have to, but think we'll be pretty close to full strength (apart from any injuries) every game because I don't see him sacrificing any competition.
Injuries will have a big say as well, I hope we don't get any more injuries but with the amount of games I don't think we will be able to avoid them.
I am sure at some point we will have to prioritaze some games more than others, I surely hope we go for the league when that time comes
