Cesc Fabregas believes Gerardo Martino's rotation policy will help prevent Barcelona from experiencing a similar slump in form as they did last season.
• Ledwith: Big decisions
Despite claiming the Liga title last term, Barca, under former boss Tito Vilanova, suffered a string of poor results in the Champions League.
The Catalan club struggled past both AC Milan and Paris Saint-Germain, before being thrashed 7-0 on aggregate by eventual winners Bayern Munich in the semifinals.
However, since taking the reins at Barca, Martino has introduced a policy of resting some of his star players, including Fabregas, Xavi, Andres Iniesta and Sergio Busquets.
And former Arsenal midfielder Fabregas feels the club will be reaping the rewards come the end of the season.
"What happened last year was a lesson," Fabregas told Marca. "We were in a mess and really weak towards the end of the season. From February on we were having to force things. We were lacking in bite at the time when everything was decided.
"Tata [Martino] is calculating the playing time really well. That will help on a physical level and in terms of competition in the squad because nobody knows who will play or who will be rested."
Barca, under Martino, have started the season in impressive form, and sit top of La Liga after winning all eight of their games.
