The 26-year-old has said that he and his team-mates are devoting the victory over Ronald de Boer's men to their grieving trainer following the death of his dad
The Catalans boss was present at Camp Nou for the victory over Frank de Boer's men in the Champions League, but is scheduled to fly home to his native Argentina following the death of his father, Jorge.
And Messi, who netted three goals in the win over the Dutch giants, says the performance was for the grief-stricken trainer.
"We played better in second half. It's a matter of time, we are adapting ourselves to the season," the 26-year-old told Canal +.
"It's good to have alternatives. We got many players to do different things and take benefit of turnovers.
"We want to dedicate it to Martino because he's not living a good moment now."
