Ronaldinho has expressed his sorrow at the death of compatriot Serginho.
The Sao Caetano player died after suffering a heart attack during a game against Sao Paulo earlier in the week.
“This is something that makes all of us very sad,” the Barcelona star stated.
“I knew Serginho from some times that I played against him.
“Now we are all very sorry and worried about what happened.
“I even don’t want to think if these things are happening more often because of the pressure that football is having on the players.”
