He should still start big games, just needs to be rested more often.
Totally agree.
We did that a bit this season, he didn't play 3 games in a row up to April. He did benefit from it too, it's been a better season than last for him. Still the weak link in the team for me.
I agree this season was overall better for him, but mostly because he needed more than half of last season to get used to Lucho's system.
Don't really agree that he was rested more this season. We didn't really have any midfield option until January because of Rafinha injury and Arda unavailability.
Just a quick look at Iniesta stats.
2014/15: He played 1.590 minutes in La Liga and 2.916 minutes overall in all competitions. He completed (played from first to last minute) just 5 league matches and 12 matches overall.
2015/16: He played 2.084 minutes in La Liga and 3.223 minutes overall with 3 games left. I think he'll most likely play all remaining games in full, so that's about 3.500 minutes or around 600 more than last season. But what's more important for me it's this - he played 19 full matches in La Liga and 26 in all competitions.
He missed 4 league games in November 2014 because of injury and this season he was injured for 3 games in October, so that's about equal.
Last season we had Xavi to sub on in last 20-30 minutes, this season we didn't have anyone except Roberto until January and then Lucho also didn't trust more in Arda and Rafinha to give Iniesta more rest. I think next season that must change and of course Denis is also coming back to give us another option. If we play 3 games per week I think Iniesta shouldn't play more than around 150 minutes in those. Whether he starts one game and is then subbed on in second half in other two or he starts two games but is subbed off in one of them around 60 minute. It's up to the schedule, injuries and form of other players when and how to rotate but I think that should be primary plan to give Iniesta enough rest, especially in first half of the season, so we can keep him fresh for March-May period, when most important games are played.
