McLaren boss Zak Brown has labelled his team’s current struggles as “completely unacceptable” following the resignation of Eric Boullier.

The team announced on Wednesday that Boullier had left the team, preempting a shakeup of the squad’s senior management.

Brown hopes it provides a degree of stability at the top of the team’s structure, after a string of team principals having come and gone in recent seasons.

“Obviously our results this year have demonstrated that we have a big performance issue,” acknowledged Brown.

“We are punching well below our weight given the history, the talent of people, the resources, and the technology at our disposal.

“This comes from a culmination of really being destabilised over many years within our team.

“If you look at our past seven or eight years we have had different CEOs, different shareholders; shareholders in, shareholders out; CEOs in, CEOs out, and have really failed to get on stable footing to be able to rebuild this great team, which is now what we are going to do.

“I think we all share in the pain of not seeing a McLaren being as successful as we know it can be,” he continued.

“It is a completely unacceptable situation we find ourselves in. It is very painful for all of us here at McLaren.”

So far in 2018 the team has amassed 44 points, more than it managed in the entirety of 2017 where Fernando Alonso and Stoffel Vandoorne scored just 30 points between them.

Brown is not expecting miracles from the restructure, though hopes it marks a turning point for the team.

“We are improving, however, we are not in a good enough place to expect to be much better,” he conceded

“We have announced this big change to get our house in order.

“The team needs to have a period of stabilisation so we can build strong foundations.

“The situation was not created overnight and therefore will not be fixed overnight, so today is our first step in getting back to winning ways.”
