Former F1 driver Max Chilton says Nico Rosberg鈥檚 decision to retire from the sport five days after winning his first world title came as a 鈥渉uge, huge shock鈥� to him.

The 31-year-old German won his first world title on Sunday, beating Mercedes team-mate Lewis Hamilton by finishing second in the final race in Abu Dhabi.

"I have climbed my mountain, I am on the peak, so this feels right," Rosberg said.

Rosberg won nine of this season's 21 grands prix, beating three-time champion Hamilton by five points.

鈥淭hat is a huge, huge shock to me鈥� said Chilton, who lined up against Rosberg while driving for the Marussia team.

鈥淚鈥檇 love to know the reasons behind it.

鈥淚 know he鈥檚 had a kid this year and he鈥檚 started a family, that might be part of it, I鈥檓 sat on the edge of my seat here blown away,鈥� he added.
