Red Bull team principal Christian Horner says Max Verstappen is free to let off steam in other motorsport series, but reaffirmed that the Dutchman’s “focus has to be” on Formula 1 following a secret test at the Nurburgring last week.

Lewis Hamilton and Max Verstappen were beaten by a shock F1 star during FP1 at the Imola Grand Prix, as a late crash ended the session prematurely. The two McLaren s were once again on top in Emilia Romagna, whilst Carlos Sainz set the third fastest time at Imola ahead of both Hamilton and Verstappen.

Red Bull's Max Verstappen is "not very" optimistic about his team’s chances of catching the leading McLaren pair in F1’s Imola GP
