Only had him for half a season, but Oliver Burke has been great for my Dortmund side. Bought him for 27M in January 19 to replace Dembele. Scored 4, assisted 4, with a 7.15 rating in 13 apps. Good in the air and tracks back willingly.
In the middle of the 3rd season with Dortmund, my starting CB pair is Kostas Manolas and Bjorn Engels. Recommend both highly. Manolas as a central defender and Engels as a ball-playing defender. Ratings through almost 20 appearances:
Manolas: 7.54
Engels: 7.66
Finishing 8th with Bournemouth is impressive, so maybe I'm off-base, but the midfield tactic/personnel looks pretty imbalanced. Utilizing Sergi Samper as your deepest player centrally seems like it would leak goals.
I would give the other CM a less adventurous role to shore that up. Maybe look...
