Van Persie: Man Utd on track for something special this season
His only medals at Arsenal both came, funnily enough, against United, a 2004 Charity Shield win and a 2005 FA Cup penalty shootout triumph.
But in both he was a bit-part player, a late substitute on each occasion.
At Old Trafford he is undoubtedly the main man and finally he has that strong and welcome feeling that his trophy drought is about to become a flood.
He said: "The way this season is going it feels like it could be very special.
"We're in a great position in the league and hopefully we can go far in the Champions League this season. But first let's focus on Real."
