Do you think this is linked to the newly decided splitting of the Menswear/Womenswear shows? Since Michele is known for his gender-fluid approach to fashion and the co-ed shows reflected that.
Who should replace him? I'd prefer someone who can keep that gender-fluidity, but wrap it in a more chic, grown-up package. Here are my ideas:
Bruno Sialelli
He has a similar aesthetic to Michele, but it's more refined and put together, something that Gucci really needs right now. His menswear needs work though.
Haider Ackermann
He's like Sialelli, but he knows how to dress grownups and has S-tier technical skills. His approach to gender-fluidity seems more sophisticated and approachable too (not overly masculine on women, not overly feminine on men). Also his links to Timothée seem to be more than Harry at the moment. That said, I'd rather have him relaunch à la Theyskens.
Riccardo Tisci
Tisci could do wonders for a house like Gucci with his background in both streetwear and couture. His more traditionally masculine approach to menswear could bring back the male clientele, who were alienated by Michele. However, I'm wary of how he'll approach the Gucci stripes (the Burberry check traumatised me).
Alessandro dell'Acqua
I consider Nº21 to be the best example of a independent modern-day fashion label and he did wonders at third-generation Rochas, so I believe he could do that on a larger scale. His menswear is meh though...
Charaf Tajer
While he claims to want of becomes the "Hermès/Louis Vuitton of his generation", Gucci could take advantage of the potential of having their own (probably more sincere) version of Virgil's Louis Vuitton if done right. Like Tisci, he can re-attract those male customers.
