The change is already defined and aims to ensure that the grass supports the volume of games during the World Cup. Thiago Jannuzzi, executive director of operations for the 2027 FIFA Women's World Cup, stated that the alteration is not just an interest, but something concrete. This is part of the requirements that were agreed upon during the bidding process and the signing of the contract.
The Mineirão will receive eight games in a period of 30 days, which could compromise the quality of the field. To address this, the fiber will be installed, which has a very high technical importance as it allows for a higher load of use. The fiber will be installed in the stadium, transforming the current 100% natural grass into a hybrid one.
The FIFA is currently studying the best date to implement the change, with one possibility being the end of this year, after the Cruzeiro's season ends. The costs for the installation of the fibers are still being discussed between the government of Minas, Minas Arena, and the FIFA.
