Kamara could always play on the half turn, Onana can't. He's just not comfortable with the football which is a slight problem.
Yup; that's it.
I wondered before the Wulfs game whether we should be playing Onana as a 10, but in the end plumped for Luiz and Bogarde as the MF pivot and Barkley as the 10. In the event UE tried what he had been starting: Luiz and Onana, with Buendia and Sancho ahead of them.
I don't rate Onana particularly highly but he does have the physique to do more. Personally, I'd be trying to offload in the summer but we probably won't becasue we have other priorities for the exit door.
