Van Vleuten joins the women’s outfit led by Sebastián Unzué for the 2021 and 2022 seasons, after five years with Mitchelton-SCOTT.
"My history with the Movistar Team goes back to many years ago. I got to know the team better as I shared training rides with them during my altitude camps in Sierra Nevada (Spain), back in 2014," van Vleuten said in a statement.
"I really liked the experience - it felt like a ‘Spanish family’ for me, I felt really welcomed by them as they were the first professional men’s team that invited me to join them in endurance training.
“With regards to the women’s team, it feels the same – I look at them like a great group of girls, with the same culture as what I saw in Sierra Nevada.
"It’s a project that attracts me, as much as I’m looking forward to working with head of performance Patxi Vila.
"I’m really looking forward to improve together with the whole team, and enthusiastic about what lies ahead with them.
"I hope they can help me becoming even faster, also on the TT bike, in combination with Canyon, which looks like a high-end bike to me."
The signing of van Vleuten - the winner of the European road title in Plouay last week - is set to help the squad sponsored by Telefónica to take a decisive step forward in its goal to become a reference in the UCI Women’s WorldTour peloton.
