Toto Wolff says it is "just a matter of time" until Lewis Hamilton signs a contract extension to keep him at Mercedes beyond 2018.
The reigning world champion has entered the final year of his contract but has been in talks about a new deal for some time. At the end of last season, Wolff told ESPN he doubted Hamilton would leave Mercedes unexpectedly, as Nico Rosberg did after winning the 2016 world championship, and it seems the discussions have continued down an encouraging path.
"Lewis has become such an important pillar within the team, it is a no-brainer that we continue with each other," Wolff told Mercedes' official website.
