The winter transfer window in Chilean football is officially heating up, and Colo Colo isn't wasting any time. The club's sporting management—led by Daniel Morón and Jaime Pizarro—has already locked in its top priorities to reinforce the squad for the second half of 2026. And they've set their sights directly on O'Higgins de Rancagua.

According to journalist Cristián Alvarado of Radio ADN, the "Cacique" is pursuing two standout Argentine players: attacking midfielder Martín Sarrafiore and right winger Francisco González. Both have been turning heads with their performances at O'Higgins, and they're now the leading candidates to fill the creative and wide-attacking roles the coaching staff urgently needs.

There's an exciting twist here, too. If both signings go through, Sarrafiore and González could reunite in Macul with their former O'Higgins teammate Maximiliano Romero—a trio that already knows how to click on the pitch.

But it's not a done deal just yet. The biggest hurdle? Foreign-player quota restrictions. Colo Colo currently needs to free up roster spots to register both Argentine talents. The board is already working behind the scenes to restructure the squad and open the necessary spaces. Expect some movement in the coming weeks as the club clears the path for these key reinforcements.

For fans, this is a clear signal: Colo Colo means business this winter. With the attack getting a major boost, the second half of the season could be a very different story.
