As someone who never watched Werner or Havertz before this year. What lineup would you use for Chelsea to get these two in their best positions. (is it even possible or is this really Chelsea buying Werner and Havertz with no place to play them with their other players)
What Lampard has done is understandable, though uninspired...especially since both Timo & Kai are still adapting to the EPL's physicality/spacing and Kai's skillset is so easily plopped into whatever role you need...and on paper, it looks similar to Leverkusen's starting lineup from last season.
But Kai hit a new level when the introduction of Wirtz on the wing allowed him to push forward, with Wirtz tucking in behind him to join the midfielders & take over Kai's creative midfield role...while Volland + a direct winger (Diaby, Bailey or Bellarabi) made runs into the wide areas to pull defenders out of Havertz' way or in behind to take advantage when Havertz drew the defenders to himself.
So with the ball their nominal:
Diaby/Bailey - Volland - Wirtz
Amiri* - Havertz
Baumgartner*
Sinkgraven - Tapsoba - S. Bender - L. Bender
shape morphed into something that looked more like:
Diaby/Bailey - Havertz - Volland
Amiri* - Wirtz
Baumgartner*
Sinkgraven - Tapsoba - S. Bender - L. Bender
*Demirbay/Arranguiz
So I'd try Ziyech in the Wirtz role, having him tuck in & playing almost like a traditional #10 with the ball...which I think might allow him to make more of an impact as well...while freeing Havertz to push further forward; with Werner & Pulisic making runs off of him. Creating something that looked like this in attack:
Pulisic - Havertz - Werner
Mount - Ziyech
Kante
Chilwell - Silva - Zouma - James
The biggest difference between that shape and the way Leverkusen played would be the FBs; as Sinkgraven & Bender were very defensive fullbacks who stayed back because they had struggled to find the right balance before replacing the more attacking FBs that they started the season playing.
But their midfield didn't have a Kante to anchor it...and even though Amiri/Demirbay are capable of matching Mount with the ball at their feet -- Amiri moreso than Demirbay, but both are nifty players -- neither is even close to as good of a presser/ball-winner. So I don't think giving your FBs more license to push forward would undermine the shape...especially since it's hard to be as dumb about it as Wendell & Weiser were
Werner is a little different, as he thrived in a striking partnership with Poulsen and Poulsen is a very unique #9. But I don't see any reason why he couldn't adapt to the role Volland filled for Leverkusen with just as much success. He has the skillset for it (even if he's not as beefy lol) and it's not that different from what he was doing for Leipzig, just more off-ball.
