After playing 30 minutes or so against Borussia Dortmund on his comeback from injury, Messi's ready to go from the start at Nuevo Los Carmenes.
"He did well I think, given the difficulty of the game, he got involved and was good," said Valverde. "(Now we have to wait for him to) add up the games and minutes to keep getting towards the optimum point of form. Yes, we expect that he can play tomorrow."
The coach also said that Messi would be rotated this year like last season.
"Last year he rotated like the rest of the players, and it caught attention because he started some games from the bench. This year the same will happen because it's inevitable with this number of games," he added.
