I think Kevin Volland is a great shout. Despite his unspectacular finishing, composure and off the ball; his work rate and teamwork make him easily the best striker outside of Cavani that isn't a regen. I know that's a bold claim, but he suits possession football so well - netted 4 goals as a poacher in a 4-2-3-1 formation that I use that isn't dissimilar to the one you're using. I had tried Jese up top and as back up for inside forward, but Volland blows him out of the water and I quickly brokoe even on Jese to cover the 30m i spent on Volland - he was just too good for Jese to stay.
Other than that, I would try improve your BBM position as it seems lacking in terms of *specificity* - De Rossi is more of a DLP-D and Garmash is good but not amazing. For this role I would reccomend Strootman super highly; but Lucas Romero and Pedro Obiang (if developed) are good shouts also. Other than that, you seem pretty stacked. Simply developing regens in your youth team and loans will make you a consistent success following your current team.
- Edit: You seem to lack a 4th CB? (Hammond might be it, but it doesn't ring a bell, regen?) If you do; I would keep an eye on Dede. His contract is up in 2017 and I got him in Summer 2016 for as little as 7m and he's superb as you would assume. Slightly jealous you got Denswil though; Porto nabbed him and are looking for 100m for him on my save.
i use same tactic an is the same team ive just sign different players we use adnan and mata as ap and rvp and lil pea as pocher
