The 26-year-old had surgery in Brazil amid fears he wouldn't be fit for the World Cup.
As said by Brazilian Brazil coach Tite, Neymar made a second-half appearance against Croatia in the worldwide friendly at Anfield on Sunday evening (June 3) and 24 minutes after coming off the bench, he found the back of the net with a stunning solo goal.
Neymar had replaced midfielder Fernandinho at halftime with the score at 0-0.

It took him just 21 minutes to make a stunning impression with a breathtaking individual goal to break the deadlock, before Liverpool favourite Roberto Firmino completed a 2-0 win in injury time.
The five-times world champions have one more friendly before the tournament, against Austria in Vienna on 10 June.

"I think he is looking forward to going back to Anfield, to Liverpool", the Brazilian said at a press conference.
