TERESOPOLIS, Brazil, Nov 15 (Reuters) - Ronaldinho's ankle injury has improved but he remains doubtful for Brazil's World Cup qualifier away to Peru on Sunday, team doctor Jose Luis Runco said on Thursday.
The Barcelona playmaker briefly took part in a practice game on Thursday but left the field early as planned.
'The injury has improved, it has progressed but he still has some limitations,' Runco told reporters.
'He felt a certain amount of insecurity and discomfort in the ankle and it is exactly this which we are looking at.'
Runco said he continued to estimate Ronaldinho's chances of playing in Sunday's game in Lima at around 70 per cent.
