Barcelona coach Tata Martino again substituted Lionel Messi during victory over Real Sociedad.

Messi was taken off with ten minutes of the game still to run.

And Martino explained: "My obligation is to take care of Messi. We need all of the players to be healthy and especially him, he needs to be healthy for the decisive moments of the season. If we have the chance, we will try to give him a bit of rest. Leo wants to play it all."
