Emery would be the most sensible choice that I can think of. Stylistically though it isn't the cleanest in terms of continuity.
Really? Aren't Villa the highest pressing team in the PL (or something like that)? Plays a back four, great defensive record (4th best in the PL), Villa were 16th when he took over.
He also has European pedigree (3 x EL wins with Sevilla, took Arsenal to the EL final and then won the EL again with Villareal). Has managed top players with 2 seasons at PSG (won 7 trophies - yeah OK it's L1).
Perfectionist who is good and managing / improving players.
I'm convincing myself here ! This is the first article I've read - I've have to read more.

Transitional attacks
Emery has tended to favour a
4-2-3-1 or
4-4-2 formation, with a heavy focus on attacking with central numbers and combinations. This usually means multiple players moving inside from wide.
His
Valencia and
Sevilla teams both employed transitional attacks in a 4-4-2 shape, but featured players who could dominate possession when necessary.
At Sevilla, Ivan Rakitic, José Antonio Reyes and Vitolo often combined in the central spaces to support striker Carlos Bacca, who attacked defenders with power and speed.
That Sevilla side was a powerful attacking unit that progressed the ball forward quickly. The rotations between Rakitic, Vitolo and Reyes ahead of the
double pivot, plus Bacca’s ability to attack 1v1, provided key attacking outlets.
In support of such fluid attacking movements, Emery has regularly fielded a solid pairing underneath the ball. This is aimed at stopping counter-attacks and sustaining possession when needed. Indeed, one trait of Emery’s sides has been recognising when counter-attacks aren’t an option and adapting style of play in possession.
In his Valencia team, central midfielders David Silva and Éver Banega were influential. At Sevilla, it was typically Stéphane M’Bia and Daniel Carriço. For Arsenal, Emery had Mattéo Guendouzi and Granit Xhaka. At PSG, the passing versatility of Thiago Motta, Adrien Rabiot and Marco Verratti linked play with those in the attacking third. At Villarreal, Dani Parejo, Étienne Capoue and Francis Coquelin were crucial in these moments.
Since taking over at Villa, Emery’s trademark transitional attacks have also been evident. The central midfield – often Douglas Luiz and Boubacar Kamara as a double pivot – have provided cover and support underneath and around the ball. When Villa regain possession, Ollie Watkins has shown the ability to link play and run in behind. He is then supported by the speedy Moussa Diaby.
Villa’s wide areas provide further support on the counter-attack. John McGinn has played wide when defending in a 4-4-2. Then, in possession, he moves to the inside channel as an extra central midfielder when needed. McGinn has also provided a box-to-box threat.
Others have been used on the opposite flank, including Nicolò Zaniolo, Leon Bailey, Jacob Ramsey and Matty Cash. All of these have provided similar transitional support to that offered by McGinn.
Sustained possession
At PSG, Emery had a squad that could dominate the ball for lengthier periods of possession than his previous teams. During his time in Ligue 1, he most commonly used a 4-2-3-1 and 4-3-3.
In the 4-3-3, Emery’s defensive midfielder would withdraw towards the central defence, encouraging both full-backs to advance (below). The front three, meanwhile, adopted a narrower shape and rotated. One of his attacking midfielders would provide a shorter passing option from defence and into attack, while the other provided a run behind the front three. These attacking movements higher up the pitch mirrored those of Emery’s previous clubs.
Defending to counter
Emery’s teams typically adopt high defensive lines in an attempt to defend away from goal. They emphasise an aggressive press and minimising spaces between the lines.
If a high defensive line is impractical, or an opponent has passed the high pressure, Emery will organise his players into a
mid-block. The double pivot he regularly utilises provides cover in front of the central defenders.
His Arsenal team relied on Xhaka, Guendouzi, Lucas Torreira and Aaron Ramsey to preserve their defensive balance when not pressing high up the pitch. Attackers Özil and Aubameyang often had wide roles without the ball so that, like Neymar at PSG, they could provide an outlet for counters.
At Villarreal, he regularly used a 4-4-2 mid-block, from which they forced play away from the centre. Having two strikers helped, with the closest attempting to restrict the ball to one side. If the central midfielders were close and narrow, they would press forwards, ready to press wide once the ball was forced there.
