Red Bull driver rift adds spice to Abu Dhabi finale

ABU DHABI : Formula One champion Max Verstappen heads into Sunday's season-ending Abu Dhabi Grand Prix facing questions about his character and behaviour after he refused to help team mate Sergio Perez at the last race in Brazil.

The Red Bull rift could bring fresh drama to Yas Marina, the circuit where last year Verstappen won his first title and denied Lewis Hamilton a record eighth in a massively controversial clash.

Verstappen has little at stake this time, having wrapped up his second title in Japan last month, but can expect a grilling from the world's media after leaving his motives a mystery at Interlagos.

Perez acidly accused Verstappen of showing "who he really is" in refusing to hand back a place as requested by Red Bull who want the Mexican to end the season second overall.
