Zico has been impressed by Philippe Coutinho's progress at Liverpool.
The midfielder is playing the best football of his career.
"Coutinho is a very skilled and tactical player," explained Zico to LFCTV GO.
"He has already played in a number of countries, which must have been a good learning experience for him as he has achieved a higher level of confidence now at Liverpool.
"This confidence has probably come from the manager and his teammates, and is something our players need when playing abroad.
"He's improved his performances as a result and you can see [last season] he was being more audacious in trying new moves and taking higher risks.
"For me, that development was important for Liverpool to have the attacking quality we saw last season."
