McLaren announced ahead of the Spanish Grand Prix that Marshall, who is a former chief designer at Red Bull, will be joining it at the start of next year as technical director of engineering and design.
His signing comes as part of a major recruitment drive that McLaren has unleashed to ensure it makes the most of a new windtunnel and simulator that are coming on tap in the next few months.
After a difficult start to the 2023 season, with its MCL60 lacking the performance hoped for, McLaren is pushing hard to find gains in the short term but knows there are huge opportunities over the long haul.
For Norris, the Marshall news was something that he is extremely excited about as he has faith it points to better things down the line.
Asked what he feels Marshall will bring to the squad, Norris said: "Just knowledge, expertise. He’s been at Red Bull for many, many years, he's seen a lot of success with the team.
"He's been with some of the best minds within Formula 1 and he's definitely part of that group.
"So, brains and lap time I guess are the two big things. He’s a big person, a big signing for us as a team, so I think someone that a lot of people within McLaren will look up to, and respect and so on.
“It is also a good step for us as a team to keep this drive forward, continuing to add performance and expertise too."
