According to sources, Neymar Jr. was fined by Barcelona for interrupting his warmup exercises to sign a boot for a fan. During last Sunday's match against Villarreal, Neymar was warming up near the stands, where he saw a fan with a boot and a marker. After jogging, Neymar approached the stands, took the boot and signed it. This was considered a lack of concentration by coach Luis Enrique, who reported the incident to Barcelona's top officers. The coach and the club then decided to impose a €6,000 fine
The same source claims that although the issue wasn't harmful, coach Luis Enrique is not happy with the player's antics on and off the pitch, so he may use this incident to set an example to other players.
