Albion are seventh in the Premier League and have delivered some encouraging performances under the Italian after he replaced previous boss Graham Potter, who left for Chelsea in September.
De Zerbi has now had ample time to assess the strengths and weaknesses of the squad as Albion hope to continue their push for Europe when their top flight campaign resumes on Boxing Day at Southampton.
The head coach wants new players to arrive in the January window and will also hope to keep his star performers such as Leo Trossard, Moises Caicedo and Robert Sanchez – all of whom will hope to see game time for their respective countries at the Qatar World Cup.
But, as it stands, De Zerbi has a core of about eight players, who are almost guaranteed a start if fit. Here, Sussex World takes a look at eight certain starters and the nine who could be on the fringes when the season resumes...
13. Billy Gilmour - ?
The former Chelsea man has had to be patient. Played well at Arsenal in the Carabao but yet to start in the PL. He will be back-up at this stage to the formidable duo of Mac Allister and Caicedo. Photo: David Price
14. Tariq Lamptey - ?
Another who performed well against Arsenal in the Carabao. Played on the left flank and that versatility will certainly improve his chances of breaking into the PL starting XI on a more regular basis. Photo: Stuart MacFarlane
15. Joel Veltman - ?
A reliable presence but the emergence of Levi Colwill makes his position a touch more uncertain. Colwill's ability to play on the left could add greater balance alongside Webster and Dunk. Photo: Ryan Pierse
16. Levi Colwill - ?
The Chelsea loanee impressed on his first PL start against Villa. Defends and blocks well and also very calm on the ball, which De Zerbi likes. Will be pushing Veltman for a starting role. Photo: David Price
