Andreas Seidl says 2021 is an "important milestone" with 2021 Mercedes switch

Andreas Seidl says that 2021 will be an "important milestone" for McLaren after they confirmed that they would be switching back to Mercedes power for 2021, following the expriation of their contract with Renault.

McLaren switched away from Mercedes for the 2015 season, making the ill-fated decision to take on Honda power, which left them towards the back of the grid for the three years they were together.

The team decided to move to Renault power for 2018, and have seen a huge upturn in form in 2019, coinciding with Seidl's arrival.

The McLaren technical director said: “2021 will be an important milestone for us as we continue our fight back to the front, so it is vital that we have the key elements in place now to enable us to prepare for the new era of the sport.
