Tata Martino is pleased with the Brazilian's recovery from injury, but insists he won't be risked if the Champions League clash with Manchester City comes too soon
The 21-year-old damaged an ankle away to Getafe a fortnight ago, and was initially ruled out for up to a month.
Martino has refused to be drawn on when the former Santos player would return to action, but says the club's record signing is responding well to treatment.
"Neymar's recovering well from the injury," Martino said at a press conference ahead of his side's game against Valencia.
"We hope he will be okay for when we play Manchester City, but if he isn't then we won't take the risk."
The Catalan giants are only top of the table on goal difference ahead of Atletico Madrid, and the Argentinian warned his players ahead of a congested month.
"We have lots of games in different competitions and in February every mistake can be costly," he said.
"Valencia are a team that are evolving, they have had some good games and they will give us a difficult time."
Barca welcome back Dani Alves, Sergio Busquets and Xavi for the visit of the Che, although Martin Montoya, Ibrahim Afellay and Carles Puyol did not make the 18-man match squad.
