It will also be very good for Chelsea because Denis Zakaria's position is as a central midfielder who in experience is very good and can help a little bit in Chelsea's midfield defense and is also expected to manage the ball forward very well.
Chelsea’s DM position has some history of black players excelling at it. The likes of Makelele, Essien, Mikel Obi and Kante. Zakaria will follow their footsteps. I can see him being very much like Essien, think he’ll do well and keep Jorginho on the bench, especially once Kante and Kovacic are fully fit.
A defensive midfielder is a position that requires strength and tireless efforts invariably must have the ability to muscle out and intercept opponents passes, I think black players tends to perform better in that role, Makelele, Essien, Mikel Obi etc did the job perfectly infact Mikel Obi was an attacking midfielder but was converted to DM by Mourinho, Chelsea is continuing with that trend invariably prompted signing of Juventus midfielder Denis Zakaria on loan as a backup for the club, meanwhile the return of Abumeyang to Chelsea will add bite to their attack with Raheem Sterling pace and quick movement as an advantage.
