Former Mercedes driver Nico Rosberg says he's surprised his former team hasn't poached technical staff from rival outfits in light of its recent design issues.
Formula 1 has seen several high-profile transfers of senior engineers between teams recently.
Aston Martin convinced former Red Bull aero chief Dan Fallows to move from Milton Keynes to Silverstone, a hiring that became effect last year.
More recently, McLaren announced that Red Bull engineering chief Rob Marshall would be joining the Woking-based outfit at the start of 2024, while team papaya also secured the services of Ferrari's chief engineer for vehicle concept David Sanchez.
Mercedes on the other hand has relied on an internal restructuring of its engineering department to improve its organization, with Mike Elliott and James Allison trading places, with the latter returning to his role as technical director.
Rosberg found it "strange" that the Brackely squad had not head-hunted senior engineers in the paddock.

"I’ve heard that Dan Fallows has also been quadrupled in salary plus an equity stake in the team," Rosberg told Sky F1.
"The teams are going for it to try and get the talent from Red Bull which is the normal way in F1. That’s what always happens.
"Mercedes – strange that they haven’t been a little bit more active there.
"The knowledge that you also get around a set of regulations when you take someone from the best team is just so valuable. Perhaps that’s a little surprising."
However, Rosberg admitted that there is still abundant engineering talent at Mercedes, expertise that will certainly be put to good use to make the most of the recent inadvertent reveal of the most defining element of Red Bull's dominant RB19.
"Then again, of course, they have incredible talent at Mercedes and now the pictures from Monaco help a lot because thanks to Sergio [Perez]’s crash," added the 2016 F1 world champion.
"There are beautiful pictures of the underbody of the car which they can now take from those pictures and create a whole CAD model and do a whole accurate design in the computer of what that car is actually doing.
"That makes it very easy to start to really understand and learn about that Red Bull car."
