Toto Wolff: We shouldn't have been 'fooling around' with costumes

Toto Wolff has criticised Mercedes' preparations for their home race after they suffered a nightmare German Grand Prix.

Whilst Saturday went to plan with Lewis Hamilton securing pole and Valtteri Bottas third, Sunday went from bad to worse as a crazy race played out at Hockenheim, where the team were celebrating their 200th race start and 125 years of motorsport with a one-off livery and period costume.

But with Hamilton finishing out of the points and Bottas crashing out of the race, marking their first pointless weekend since Austria last year, Wolff suggested their eye was off the ball this weekend with them "fooling around" with costumes and liveries.

"I think we had a decent start with good pace. Then you had incidents, crashing out in tricky conditions, the wrong calls," he explained.

"It was unfortunate [for Hamilton], crashing right at the entry of the pit lane. You are not prepared. We made the wrong calls afterwards [but then] it was all coming together as many drivers crashed.

"Overall for us it was a bad day, for the drivers it was a bad day, it cannot go much worse.

"This shows that you shouldn't fool around with stuff. You should concentrate on the job. We are not superstitious but we believe in karma and it's a day to learn."
