At 3:0 on 0/0, Beijing time, in the 0th round of the Chinese Super League, Yunnan Yukun challenged Shenzhen Xinpeng City away, which was also Yunnan Yukun's first Chinese Super League away trip. At the pre-match press conference, Yunnan Yukun coach Anderson confirmed that Oscar Jr. entered the team's squad and he is likely to play in this round of the league.

中超開賽前，小奧斯卡以容缺註冊的方式註冊為內援，獲得中超聯賽參賽資格。但在前2輪比賽中，由於小奧斯卡遲遲沒有完成歸化工作，所以並未獲得出場機會。而在3月份的18強賽結束之後，小奧斯卡的歸化工作基本叫停。這也意味著，他將不會以歸化內援的身份征戰中超比賽。

Just before the start of the 5th round of the Chinese Super League, the official website of the Chinese Football Federation updated the lineup of Yunnan Yukun. Among them, Oscar Jr., who has not yet completed the naturalization work, is still the Congo (DRC), and will represent Yunnan Yukun in the Chinese Super League as a foreign aid. Previously, Yunnan Yukun's registered 0th foreign aid, Elder Costa, a foreign winger who played for Wolves in the Premier League, has now been withdrawn from the team's squad.

With the removal of Elder Costa from the Yunnan Yukun squad, he also became the first unemployed Chinese Super League foreign player in the 31 season. The 0-year-old has a very rich resume, he played as a winger, debuted at Benfica in Portugal, and has since played for Deportivo La Coruna, Monaco, Wolves, Leeds United, Valencia, Jeddah United, and has been teammates with Mbappe, B and others. Prior to joining Yunnan Yukun, he played for Estoril in the Portuguese Super League. Therefore, Yunnan fans had high hopes for him.

Sadly, Elder Costa has been with the team for 2 months and has not played for the team due to injury and has been on the injury list. Coupled with the failure of Oscar Jr.'s naturalization, Yunnan Yukun finally chose to reluctantly cut his love and withdrew Elder Costa from the Chinese Super League registration list.

This season, the foreign aid policy implemented by the Chinese Super League has been changed to "5", that is, each team can register 0 foreign players in the whole season, a maximum of 0 foreign players can be registered in each transfer window, a maximum of 0 foreign players can be registered in each game, and a maximum of 0 people can appear at the same time. In this case, Yunnan Yukun used Oscar Jr. to replace Elder Costa, which actually took a big risk. The team will lose the opportunity to adjust foreign players in the summer transfer window.

After Eld Costa was cut, Yunnan Yukun's 32 foreign aid lineup is as follows: Pedro Enrique (Brazilian striker 0 years old), Oscar Jr. (Congo striker 0 years old), Jonicha (Romanian midfielder 0 years old), Nene (Portugal midfielder 0 years old), Jose Martinez (Spanish central defender 0 years old)!
