McLaren’s form is ’embarrassing’ after Spanish Grand Prix disappointment, admits Jenson Button

However, despite a raft of upgrades on the MP4-28, McLaren failed to secure a
satisfying result.

“We’ve got a lot of work to do,” said Button.

“There’s a lot of useful information to go through from the new parts on
the car and we’ve got some other parts coming for Monaco, too.”
