Chivas has not received an official offer for Diego Campillo, and there are reports linking him to Olympiacos. The Greek club is reportedly interested in Campillo as his contract is set to expire this December. Journalist Juan Adrian Simendal Satarain from soyfutbol.com reports that Olympiacos has targeted Campillo as a free agent, is giving serious consideration to acquiring him, and is hopeful of persuading him not to renew his contract with Guadalajara. Olympiacos is closely monitoring Campillo and might make a move during the winter transfer window. It is rumored that Campillo is a significant target for Antonio Cordon. If Campillo does not renew his contract with Guadalajara, he will be permitted to negotiate with any club, and Olympiacos could be in a primary position to negotiate with him.

Olympiacos is interested in 25-year-old Chivas central defender Diego Campillo. The Greek club previously acquired another player, Armando González, from the same Mexican team two months ago. Campillo is a starter for his team, has played once for the Mexican national team, and has a contract that expires in three months on December 31. He joined Deportivo Guadalajara in July 2025 and has a current Transfermarkt market value of €6.00m.
