Allen on the other hand doesn't deserve anything IMO.
We can instead rotate with Can, Lucas, Henderson, Coutinho, Sterling, Lallana and SG - leaving two of them out every match.
The midfield should then look something like this:
--------Lucas----Can---------
---Lallana---SG---Sterling---
Or:
------Henderson----Can-------
--Lallana-Coutinho-Sterling--
Or any other combination that might look promising. Where Allen would fit in I just don't know!
