Horner admits to challenging campaign
Red Bull Team Principal Christian Horner has admitted his side are in the midst of a challenging Formula One championship.
The season so far has been dominated by the use of the new Pirelli tyres, which has created the unpredictable nature of the campaign after the first seven races.
With seven different drivers claiming chequered flags this term, it's difficult to predict who will claim the win in the next meeting in Valencia for the European Grand Prix.
Horner has dismissed the claims the Formula One season has become a lottery but has admitted that getting a consistent performance out of the car has become the real test.
He said: "I think (the word) lottery is too harsh, but I would say it's certainly challenging.
"You are trying to make judgements through a race based on the feedback you have from your own car and the information you have around you, and it's tricky."
