(Reuters) - Seven times world champion Lewis Hamilton is under "way more pressure" than his Formula One title rival Max Verstappen, Red Bull team boss Christian Horner said on Friday.

Verstappen, 23, leads Mercedes' Hamilton by five points in the championship after 14 of 22 races but will start Sunday's Russian Grand Prix from the back of the grid after an engine change.
