VALENCIA (AFP) - German world champion Sebastian Vettel will start from pole position in Sunday's Formula One European Grand Prix after the Red Bull driver was fastest in qualifying here on Saturday. The 26-year-old - who leads this season's championship - will start alongside Australian team-mate Mark Webber, who was second fastest, while Britain's 2008 world champion Lewis Hamilton will start on the second row in his McLaren. Ferrari's Fernando Alonso will start from fourth spot. Formula One leader Sebastian Vettel was fastest in the final practice session before qualifying for Formula One's European Grand Prix on Saturday. The Red Bull driver clocked 1 minute, 37.258 seconds around the Valencia street circuit to lead Ferrari pair Fernando Alonso and Felipe Massa in hot, muggy conditions along the harborside course. Alonso, who was quickest in Friday practice, went around the America's Cup port in 1:37.678 while Massa was a further one-tenth slower. Mark Webber of Red Bull was the only other driver within one second of the reigning F1 champion after the Australian finished with a quickest lap of 1:38.068. McLaren's Jenson Button, who is coming off a Canadian GP win, was fifth while Nico Rosberg of Mercedes split Button from McLaren team mate Lewis Hamilton, who trailed Vettel by 1.483 seconds. Red Bull has started all seven races from pole position this season with Vettel winning five of those. Vettel leads Button by 60 points in the standings with 161 points, while Webber is third ahead of Hamilton, who is the only other race winner this season. Two-time world champion Alonso, who retired early in Montreal after a second-place finish in Monaco, is desperate for victory in front of his home fans, with Ferrari's championship hopes sputtering so far this season. The track temperature, which touched 41 degrees Celsius (106 degrees Fahrenheit) during practice, is expected to heat up for qualifying later ahead of Sunday's 57-lap race. Red Bull chief denies Hamilton move: Meanwhile, Red Bull team chief Christian Horner on Saturday rejected all suggestions that he was scheming to bring in Lewis Hamilton to partner Sebastian Vettel in an F1 'super team'. Horner said that much as he admired 26-year-old fellow-Briton Hamilton, who he has called a "uniquely, supremely-gifted driver", he had no intention to sign him as a replacement for Australian Mark Webber, 34. Instead, he said, it was far more important that he and Red Bull looked beyond the attraction of a dynamic duo of names on paper and considered the reality of achieving more with a harmonious team. Horner said: "Lewis is a great driver. He's a McLaren driver so it's not even something we're thinking about. We're happy with the two drivers we've got. "I think it would be interesting. They're two of the best guys in the world, but sometimes, as a team, you've got to look beyond what looks most attractive on paper. It's all about harmony and about the team at the end of the day." Speculation surrounding the future for the Red Bull team and Hamilton was sparked when the British driver visited their motor home during the Canadian Grand Prix two weeks ago. Hamilton and Red Bull both dismissed the visit, during which Hamilton and Horner met and talked for 20 minutes, as purely social. Hamilton has since made clear that he wishes to remain at McLaren, but his actions have been interpreted as an attempt to help his negotiating position. He has a contract to the end of 2012. Hamilton, the 2008 champion, is currently partnered by fellow-Briton Jenson Button, the 2009 champion, in a team of two ambitious and highly-talented drivers. 1st row Sebastian Vettel (GER/Red Bull-Renault); Mark Webber (AUS/Red Bull-Renault) 2nd row Lewis Hamilton (GBR/McLaren-Mercedes); Fernando Alonso (ESP/Ferrari) 3rd row Felipe Massa (BRA/Ferrari); Jenson Button (GBR/McLaren-Mercedes). 4th row Nico Rosberg (GER/Mercedes); Michael Schumacher (GER/Mercedes) 5th row Nick Heidfeld (GER/Lotus-Renault); Adrian Sutil (GER/Force India-Mercedes) 6th row Vitaly Petrov (RUS/Lotus-Renault); Paul di Resta (GBR/Force India-Mercedes) 7th row Rubens Barrichello (BRA/Williams-Cosworth); Kamui Kobayashi (JPN/Sauber-Ferrari). 8th row Pastor Maldonado (VEN/Williams-Cosworth); Sergio Perez (MEX/Sauber-Ferrari). 9th row Sebastien Buemi (SUI/Toro Rosso-Ferrari); Jaime Alguersuari (ESP/Toro Rosso-Ferrari). 10th row Heikki Kovalainen (FIN/Team Lotus); Jarno Trulli (ITA/Team Lotus) 11th row Timo Glock (GER/Virgin-Cosworth); Vitantonio Liuzzi (ITA/Hispania-Cosworth) 12th row Jerome d'Ambrosio (BEL/Virgin-Cosworth); Narain Karthikeyan (IND/Hispania-Cosworth)
