Title: Lille's Transfer Deal With Chelsea to Sell Key Midfielder for €35 Million

The transfer window is closing in France as Ligue 1 giants Lille and Chelsea have struck a deal to bring together their key midfielders, leaving the French champions with a significant sum on the table.

According to reports, Chelsea has agreed to pay Lille €35 million for the services of Pierre-Emerick Aubameyang and Diego Costa, both of whom were among the stars of the Premier League this season. The move is set to be completed by the end of the month, after which it will be up to Lille to decide whether they want to retain Aubameyang or sign him permanently.

Aubameyang was one of the most influential players in the Premier League last season, scoring 26 goals and providing assists for his team-mates. He had a strong impact on the Blues' success and was a key player in their title-winning campaign.

Costa, on the other hand, was a versatile striker who could provide support to the front-line if he were to remain at the club. He also scored five goals in the Champions League this season, making him a valuable addition to Chelsea's squad.

However, Lille may not be happy about the deal, especially given that they already have some of the best strikers in Europe. They are hoping to strengthen their attacking options before the start of the new season next year.

In conclusion, the transfer deal between Lille and Chelsea is set to be a major coup for the French champions. It is hoped that the two clubs can work out a mutually beneficial arrangement and ensure that they continue to develop their respective talent pools.
