Barcelona midfielder Arthur Melo has apologised for attending the birthday party of PSG star Neymar.

The 22-year-old travelled to Paris two days before the Copa del Rey derby against Real Madrid and admitted that he shouldn't have.

"I think I was wrong and these things happen in life, as sometimes you're wrong and sometimes you're right," he told a press conference prior Wednesday's game against Lyon.

"I was excited to go, but I'm old enough to take responsibility as I knew what I was doing and I apologise if I bothered anyone.

"My teammates have helped me a lot to recover from my injury and I am grateful to them.

"I am happy to have recovered.

"I will give my best and I know I have to improve as a person."
