Mercedes may rethink team order plan

Mercedes say they may be forced to rethink their policy of letting Lewis Hamilton and Nico Rosberg race freely. The team's current approach led to a thrilling duel in the Bahrain Grand Prix, when Hamilton won a race-long battle with his team-mate. But team boss Toto Wolff says they may need to adapt if their rivals catch up. "There might be situations where you can't lose lots of time in battle if you have your enemy right up your back," he said.
