Lacazette has been in top form this season, scoring 8 goals and providing 4 assists in his first 7 matches for Lyon. His performance is impressive given that he was recently linked with a move to Chelsea, but he has made it clear that he wants to stay at Lyon.

The origin of the best returning player award is not entirely clear, but it seems that Lacazette may have won it based on his recent performances. The award, which is presented by French football magazine Foot Mercato, recognizes players who have returned to their club after being sold elsewhere. In Lacazette's case, he left Arsenal for Lyon in January 2019.

Despite being a transfer away from Arsenal, Lacazette has been one of the most consistent performers for Lyon this season. He has shown great skill and ability on the pitch, and has helped Lyon to maintain their position in the top flight of French football.

It remains to be seen how Lacazette will fare in the future, but his current form suggests that he could continue to perform well for Lyon. If he continues to play at this level, he could potentially win more awards and recognition in the coming years.
