Vettel rivals 'encouraged' booing

Red Bull team boss Christian Horner says Sebastian Vettel's rivals have encouraged the booing of the four-time world champion. $render("advert","advert-companion","24204366"); $render("advert-post-script-load"); Singapore Grand Prix: Sebastian Vettel booed on podium after win require( ["sportui/empswitch"], function(empswitch) { empswitch.init(); } ); Vettel, 26, has been heckled by Formula 1 fans at many races this season. The German's domination and ignoring orders not to pass team-te Mark Webber at the Malaysian Grand Prix are cited as reasons for the booing. Horner said: "It is difficult for him to handle. Whilst he's not betrayed it, he's felt it and not understood it." Webber led after the final pit stops of the Malaysian Grand Prix in March and the drivers were told to hold position to the end of the race, but Vettel passed Webber after a tussle with 13 laps to go. Vettel later apologised for the incident. Horner, who was interviewed by England's rugby World Cup-winning coach Sir Clive Woodward for a special programme broadcast on BBC Radio 5 live on Wednesday, also said: "The perception comes from what happened at Malaysia and that he stole a win from Mark Webber. He was then portrayed as the bad guy.
