Fernando Alonso said he will be available to help Renault with "anything they need" for the remainder of this season as he prepares to make his Formula One return next year.
Renault announced in July that Alonso will partner Esteban Ocon in what will be a rebranded Alpine F1 Team from 2021.
The two-time F1 world champion has spent time at Renault's Enstone base this week as he gears up for his comeback.
Alonso was delighted to be back at the team where he was crowned champion in 2005 and 2006 and the Spaniard is prepared to pass on his experience before taking his place on the grid.
He said: "Being back at Enstone was a very good experience, they were very emotional days.
"A lot of things have changed; the simulator is new, the wind tunnel has been updated, but a few things are the same: there are the same offices, the gym that I used to visit a lot…
"It was a like a first day at school, with lots of things to learn and get through, but it was very productive. I've followed a programme in the simulator, getting used to the car a little, testing the facilities – last time I was here the simulator didn't exist! Then I had a seat fit and meetings with key people to understand the programme for next year. It was really just getting up to speed."
He added: "I think the team is in good shape for the future. The last few races were encouraging for everyone, for myself too.
"To see Renault back in a competitive manner is a good thing for the sport and I've been delighted to see the improvements.
"We've still got a long way to go and the midfield is very tight but I think the guys have done an amazing job trackside. The last couple of races were very exciting to watch and I am looking forward to being back in the mix.
"I'll now follow what the team needs from my side – some sim days, helping some weekends and being available for the team for anything they need."
