However, de Minaur was quick to jump to the defence of his teammate, stating that he doesn't think the call will cause any harm and that Kokkinakis is being unfairly targeted.

The Australian No.1's comments have been met with a mix of reactions, with some praising his loyalty and others questioning his judgment.

Despite the backlash, de Minaur remains steadfast in his support for Kokkinakis, and the two teammates are expected to put aside the controversy and focus on their upcoming matches.

The drama surrounding Kokkinakis has brought attention to the strong bond between de Minaur and his Davis Cup teammates, and the Australian No.1's willingness to defend his friends and family is a testament to his character.

As the tennis world continues to buzz with news of the $1.2m call, one thing is certain - de Minaur and Kokkinakis will face their upcoming challenges with the support of their teammates and the Australian tennis community behind them.
