You could save on Lovren by down grading him to Clyne or Shaw (depending on their injury status)
SWA have a very tough schedule so I'm not going near their defence but they do have the abilities to get CS when not expected.
I'm steering clear of Man City due to the rotation issues. I think there are much better and more reliable options who have equally appealing games (e.g. LIV or TOT)
Why Fer and not Snodgrass for 0.5m more?
vWw - Not yet convinced. I think there are better options at the moment such as Rodriguez from SOT. I'd be tempted to downgrade Aguero to a 9m FWD and upgrade vWw to a 9m as well.
