Sebastien Buemi has hinted that a frosty edge has grown on his relationship with Toro Rosso teammate Jaime Alguersuari.
Before the start of the season, with Daniel Ricciardo expected to take one of their seats for 2012, Spaniard Alguersuari admitted 2011 will be "war" with Buemi.
In Australia, 22-year-old Buemi reacted angrily when the sister STR6 collided with him at the start, only for Alguersuari to then reveal it had been his teammate at fault for the mysterious clash with Nick Heidfeld.
The correspondent for Blick newspaper reveals that on the Frankfurt-Kuala Lumpur flight this week, Buemi sat directly in front of Alguersuari but they endured "over 12 hours of silence".
"We spoke after his foul in Melbourne," Buemi revealed. "We both had a different opinion. I hope he does the right thing now and respects me.

"I don't want to say any more about it," he added.
Meanwhile, Swiss Buemi benefited from the disqualification of Switzerland's F1 team Sauber in Australia, moving up two places in the lower points.
"I feel sorry for the Swiss team," he admitted, "but they are fast enough that they will succeed again soon. "I think that in 2011 we will have a good fight with Sauber and also Williams," continued Buemi.
