Despite scoring a wonderful opening goal against Croatia at Anfield, the 26-year-old says he is still seeking full fitness
Neymar says he is at "80 per cent" after scoring a superb goal on his return from three months out with a broken foot.
Brazil's talisman opened the scoring in a 2-0 win over Croatia as Tite's men warmed up for the World Cup with a straightforward victory at Anfield on Sunday.
Neymar's goal, a thumping finish off the crossbar after beating a trio of defenders, showed the Paris Saint-Germain star at his best.
But Neymar insists he is not yet fully fit and is still concerned he could aggravate the injury that ruled him out of the end of the domestic season.
