He did fine against Stoke City. He looked sharper, quicker, and was better on the ball than against Hull (in the first half). However, Stoke's game plan made it difficult to play as he normally does this season, and I was very surprised that he didn't adjust his game to overcome Stoke's defensive game plan, especially with Wilson around, who's skill set is currently more specific than van Persie's.
In this match, with Stoke sitting so deep and our midfielders dragging theirs away to create spaces in the middle, van Persie should have popped into those spaces and drag the Stoke defenders away, creating running avenues for Wilson, Mata/Herrera, etc. However, he didn't do this, and Wilson and van Persie were essentially playing the same exact role for much of the match, which resulted in our attacks being slower, and our play being less incisive, particularly in the first half when Stoke kept it tight in the middle and defence.
In the second half, we only got better once Stoke started pushing and creating gaps for Mata and Herrera to exploit. Otherwise, only Wilson changed his game slightly to drag the defenders away so he could beat them with this runs. van Persie was, as usual, playing more like how I expected Wilson to play in this match.
Something happened under Moyes. van Persie completely changed his style of play under him, and other than the World Cup campaign, he hasn't really looked like what he was before Moyes came here. Nowadays, he's pretty much playing like a traditional striker with others having to either change their game for him (Falcao, Wilson) or Rooney having to help make our attacks more incisive. With Falcao and Wilson, van Persie needs to control his selfishness and work more for the team with drawing defenders away from the back line. This way, his partner will do more of the same, and we can have a stronger attacking setup. However, van Persie's played more strictly than I would expect him to with Falcao, Wilson, and Rooney having to do what van Persie should also do every time. This makes it easier for the opposition to close van Persie down unless his partner does the job of dragging defenders away.
Personally, I feel like van Persie is becoming obsessed with scoring goals, which is why his movement, positioning, and overall game is set up as it currently is and not what it naturally should be. In this case, we must play Rooney alongside him in order to break down defences like Stoke's in the first half. With two strikers just staying up front and trying to get into the box, we will have a tough time breaking down teams parking the bus unless one of the strikers drops a little bit back into the hole and drag the defenders away, which Rooney and Falcao do at the moment.
