Football fans have reacted furiously to Neymar's father who has backed the Paris Saint-Germain (PSG) forward after he seemingly confessed to infidelity.The 31-year-old uploaded a post on his Instagram account on Thursday (June 21) apologising to his pregnant partner Bruna Biancardi:"I made a mistake. I was wrong with you. I dare say that I make mistakes every day, on and off the field. But my mistakes in my personal life I resolve at home, in my privacy with my family and friends... All of this reached one of the most special people in my life."

Congratulations (love)."This came after it was widely reported that the PSG forward had cheated on Biancardi in the last week. However, the player's father's comment has been met with strong backlash from fans. Many think the Brazilian's father's comment is ill-judged, given the circumstances.One fan was particularly scathing, questioning the morals of the PSG attacker's family:"Neymar cheats on his pregnant gf, and his dad replies with “congratulations” for what? Publicly apologising? This family needs a reality check so bad!"Another fan reacted in anger, lashing out at the Brazil international's father:"Neymar's dad is a sicko."Here's how Twitter reacted to Neymar's father's response to his son's apology:Sahini👸@sahini1001Neymar cheats on his pregnant gf and his dad replies with “congratulations” for what?
