The midfielder hopes that the Brazilian will not allow the tax issues raised by his move from Santos to Catalunya last summer affect his concentration
The 22-year-old forward's name has been dragged into separate court cases on either side of the Atlantic Ocean over the financial legality of his move to Camp Nou.
Neymar's former club Santos is pursuing his father with an injunction as it seeks to see the documents that confirm the 40 million euros that Barca agreed to pay him in 2011 if he joined Camp Nou.
Meanwhile in Spain, the Catalunya club has been charged for failing to declare a taxable amount of 37.9 million euros in the transfer of the Brazil international, with the Spanish justice system seeking 9.1 million euros in reparation.
Neymar has already felt compelled to defend his father against claims made by Santos club officials in an angry tirade, but Barca teammate Xavi is not concerned about all of the drama as long the Selecao star maintains his impressive form on the pitch.
"The most important thing is that this doesn't affect Neymar professionally," Xavi told reporters in Spain on Thursday. "Right now he is happy and working back from his injury.
"I don't think it's affecting him - the other day he came on for a few minutes and scored a fantastic goal."
Neymar's had spent a month on the sidelines with an ankle problem as the furor around his transfer unfolded before his goalscoring return off the bench against Rayo Vallecano last weekend.
