That would give us an attacking midfield trio of Pienaar, Mirallas and de Bruyne. Barkley as sub.
Lukaku as lone striker. Anichebe and Jelavic as good options such as in a 4-4-2. However from the bench Anichebe is the better impact player so I can see Jelavic possibly leaving if Moyes receives a good offer.
Then, whatever the remaining money from TV deal can be used to get a combative B2B midfielder like Felli, such as Fer. I'm sure Moyes has a few targets.
Any money from sales of players such as Heitinga, Naismith or Jelavic may then be used to get a future Sylvain Distin or Steven Pienaar. If Mucha leaves we need a new no. 2 keeper
Howard
Coleman Jagielka Distin Baines
Gibson Fer
Mirallas de Bruyne Pienaar
Lukaku.
Of course, this is all FM like speculation (but it is fun to do so). That team would be good improvement in terms of finishing chances and not getting out-muscled in midfield, and, with younger players it will continue to get better over time.
Weaknesses still would be distribution from CB and GK and long range shooting skills of the entire midfield. Barkley's lookin good in that aspect though.
