Red Bull team boss Christian Horner says the aggressive strategy used to help Sebastian Vettel take victory in the Spanish Grand Prix is unlikely to work this weekend in Monaco.
The team called Vettel in for his first stop in Barcelona while running in second place, despite the fact that it meant the German rejoined in traffic amongst the drivers fighting lower down the top ten.
A series of impressive overtaking moves meant the defending champion stayed close to Fernando Alonso on track before jumping ahead of the Ferrari in the second round of stops – going on to take his fourth win in five races this season.
However, Horner admits that such an approach – which relied on Vettel being able to make up places after his stop – wouldn't work if employed on the streets of Monte Carlo.
"We were really aggressive in Barcelona, which relied on Sebastian making passes which were tough, but not impossible," he was quoted by Sky Sports
. "It was a bold decision and it paid off. The question is: are you going to have the bravery to do that in Monaco where generally overtaking is impossible?
"I'm not sure that would work in Monaco. Quite simply I don't think we will be able to drive past someone like Jenson as we did yesterday. So it's going to be fascinating to see how teams apply strategy to the race, as well as see how they manage the tyres."
Horner added that Vettel's performance in getting to the front and then seeing off the challenge of Lewis Hamilton's McLaren was 'phenomenal'.
"Seb just couldn't quite break him [Hamilton," he said. "But it's very difficult because you know if you abuse the tyres then you might run out towards the end of a race.
"So you need tremendous mental poise to deal with that, especially when you are leading a grand prix, but he coped tremendously well.
"He's peerless when he's in a situation like that. He drove a phenomenal race, and it was fantastic to see him get the win."
