Button: McLaren's current pace is unacceptable
Jenson Button insists McLaren needs to make a drastic step forward with the upgrades it plans to bring to Spain as its current form is "not good enough".
McLaren was optimistic coming into China that it had the pace to be the best of the rest, but it found itself off the pace of Red Bull, Ferrari and even the other two Mercedes factory teams Williams and Force India, with Button finishing 11th. A combination of issues with tyres and low downforce hampered McLaren all weekend in Shanghai and Button admits he is not sure why the team fell so far behind.
"We've got some upgrades coming, but we were a lot further behind [in China] than we were in the last race," Button said. "We just aren't quick, I don't think people brought that much so I don't know what we are doing really. China was disappointing for the whole team, when everyone works hard and you have such a bad result it's tough, especially for the guys back in the factory. Hopefully they can stay positive and keep updating the car because at the moment this isn't good enough."
After the race, Button admitted McLaren was struggling with tyres in both wet and dry conditions and that he is unsure what the issues are.
"We can't get the fronts working, they just grain. If we knew the problem with the tyres we could have solved it, so hopefully we will have some more information in Spain."
