Christian Horner has played down hopes that Formula 1's new tyre rules will really spice up the action.
From 2016, a set of complex rules essentially allowing teams to choose from three tyre compounds per race is tipped to shake up the established order.
"It's a nice way to give [teams] a few more options," the Red Bull team principal told L'Equipe.
"It may inject a little more variability into the races, but I fear that with the very powerful simulation we can do these days that most of the teams will be making the same choices."
The new season gets underway in Australia on March 20.
