Toto Wolff dismissed the idea of a "waste of time" chat with Red Bull chiefs over a potential deal for Mick Schumacher.
The German is a reserve for the Silver Arrows this year. But he will not want to be in that position for too long as his ultimate ambition is to establish himself on the grid.
Haas let him go at the end of last season, having not seen enough to convince them to offer him another deal. And Wolff wasted little time before bringing him into the Mercedes fold.
