DeBryune as a false 9 and Fernado at DM will work too.
But really, I think our biggest problem for the longest time has been a lack of individual dribblers who take on players and disrupt Defensive lines. Sterling is the only starter we have with that ability. The sooner Sane and Jesus can join him, the better. And perhaps we should be looking at signing one more pure dribbler Musonda or Peirrera, players of that ilk who disrupt defenses by running at them.
Every article I read talks about our problems on defense, but for my money our inability to break down defending teams is just as much if an issue. Sterling now, Sane soon and Jesus hopefully sometime this season should help us alleviate some of that problem.
The Central midfield too can do with a burst of energy and quicker play.
I think Liverpool and Spurs will make top 4. They both play very good football. Chelsea also coz they caught a good run. Don't think they are as good as Pool or Tothenham though.
Thus, one of Arsenal, United or us will get the last spot. In spite of our struggle, I still like us over those 2 for now. But the margin is slimmer than ever. Everyone is getting better but we seem to be stagnant. :(
