I've said it previously but you can see the development in Silva's all round game.
When he first joined he looked like he'd struggle to run into a gentle breeze but he did often find himself getting half decent chances when he got on the pitch just that his finishing, particularly with his head, was often too tame. Last season he looked like he's much better equipped to compete physically with defenders, even if he wasn't going toe to toe as such and shrugging people off he was at least using his body well to shield the ball and buy fouls for his efforts. Didn't seem to get himself into goal scoring positions as frequently though.
I think the two could possibly be linked. When he was unable to compete properly in the wider game it made sense for him to focus purely on being in the right place at the business end. Find the gaps wherever you can, avoid the physical battles and hope someone can pick you out or you get a lucky run of the ball, which kind of worked for him to an extent. Now he's got a bit more in his locker it's drawing him into other parts of the pitch and being involved in moves earlier which naturally draws him away from the 6 yard box. We've seen him running the channels a lot more this season than last, with mixed results.
Now it probably needs a bit of focus, both with him as an individual and the wider team, to make sure he can put himself to use in the most effective way. He needs to balance being that outlet and providing the interplay to build attacks alongside getting into the box to try to finish them off. You can say the exact same thing of Jimenez too, who seems to have had a complete reluctance to attack the 6 yard box this season, not that it was ever really his calling card before that.
