The Mercedes Formula One team that their technical-side Executive Director Paddy Lowe will be leaving the team after three and a half years. His likely (though still unconfirmed) destination is Williams, reports . Williams has to receive someone in exchange for letting Finnish driver Valtteri Bottas go, and are saying Paddy is it.

Lowe was instrumental in Mercedes’ absolute nailing of the new turbocharged V6 hybrid spec and utter and thus, the team’s complete domination of F1 for the past few years, so needless to say, he’s a in exchange for Williams’ fast Finn. Lowe previously worked for Williams earlier in his career, over twenty-three years ago.

Our international nightmare of waiting for Mercedes to finally, finally, finally officially announce Valtteri Bottas as Nico Rosberg’s replacement is almost over. NBC Sports notes that Bottas’ announcement is expected later this month.

A source who claims to be close to the team who emailed Jalopnik denies that Lowe is moving in exchange for Bottas, but rather, more out of frustration with Niki Lauda’s constant meddling with the Mercedes team, and claims Lowe has some “unfinished business” at Williams. (From 23 years ago? Okay.) We’ll see how it all pans out, regardless.
