Chelsea midfielder Oscar was recently signed by Chinese Super League team Shanghai SIPG. Oscar was sold for a reported fee around £60 million, according to Sky Sports. Chelsea released a statement on their official website, which stated:

Chelsea Football Club and Shanghai SIPG have agreed terms for the permanent transfer of Oscar.

The 25-year-old will join the Chinese Super League team at the beginning of the January transfer window. 

Chelsea made a profit of around £40 million on the Brazilian midfielder. But this transfer has raised suspision in the eyes of Arsenal manager Arsene Wenger. Wenger said, in a recent interview with Sky Sports, that the money in the Chinese League is a major concern

Yes, it's a surprise, it's a distortion. Basically when you're a football player you want to combine the quality of the competition with the quantity of your wages. 

It's a surprise to me, but when I was in Japan, we had many Brazilian players. At the moment I think Oscar moves because he doesn't play in the Premier League. China gives him that opportunity as well. They invest a lot of money at the moment.

Will it be a future problem for the Premier League? It could become.

The 67 year old manager also expressed similar concerns when the world transfer record was broken when Manchester United signed Paul Pogba for a fee of €105 million. When asked about Pogba's fee earlier on in the season, Wenger said:

It is completely crazy if you cannot afford to pay it. If you can afford to pay it you can justify it. It is completely crazy if you compare it to normal life. That is for sure. But we live in a world where every activity that is worldwide makes a lot of money.

Liverpool manager Jurgen Klopp, did not share Wenger's concern. He likened China's situation to that in England.

You know that the rest of Europe thinks the same thing about England. If a player decides to go there, usually it's in another part of your career.
