Barcelona is in talks to sign Oscar this January window.
The former Chelsea midfielder joined Shanghai Port in 2017 and is expected to make a possible return to Europe this year.
He earns £540,000-a-week in China and the wages could be a stumbling block for Blaugrana.
However, Barcelona could sign him on a six-month loan and pay him a small percentage of his salary.
“Barcelona reached out to my agent to know about this possibility, they knew football in China will stop until March. So maybe, but Barca is facing a difficult time now,” Oscar said.
“I was told about this interest, I guess they’re still trying to figure something out. Barca has this issue about registering new signings and they’d still need to sort talks with my club.
“They would want for me to join until the end of the season. They’re still talking, it’s ongoing, but there’s this problem with the new signings – I guess Dani Alves has faced some.
“It’s nice to see a great club interested in you. We didn’t have any talks so far, there’s no point doing that if Barcelona can’t register new players right now. Barca is trying to sort their end out, then maybe I’ll talk to my agent so we can arrange something.
“It’d be an incredible opportunity for me, for Barcelona too. I’m in great form here, it would be great for my career.”
