Brundle sees 'challenges' for Red Bull if Horner departs F1 team

Will Christian Horner be on the pit wall as Red Bull Racing team boss at the Bahrain Grand Prix on Sunday, or will the Brit watch the race as an unemployed man? A decision on whether or not Horner will stay on is likely to follow shortly, at least before the start of the opening race. In the event that Horner is found guilty of inappropriate behaviour, Red Bull Racing will face "challenges", believes Martin Brundle.
