SHANGHAI, April 21— Red Bull’s triple world champion Max Verstappen has more depths to him and so could consider a move to rivals Mercedes, even though he is currently in the quickest Formula One car, Toto Wolff, the German team’s boss, said today.

Speculation that the Dutch 26-year-old might leave the current champions arose earlier this year after allegations against team principal Christian Horner of misconduct towards a female employee, which he was later cleared of although they stoked rumours of divisions within the team.
