Why Perez has not been replaced: 'It's a head-scratcher for Red Bull'

The British Grand Prix was another poor weekend for Max Verstappen's teammate Sergio Perez who has scored 15 points in his last six races. Although the Mexican has signed a two-year extension with Red Bull, questions are being raised over whether this was the right decision. Speaking on the Sky Sports F1 podcast, Martin Brundle explained why the team have decided to keep him, and who he thinks could become a potential replacement should he not perform.
