Ian Wright makes that comparison. He knows what he's talking about when it comes to strikers.
Yes, I want Theo to play up front or on the left of the 4-3-3 but again, you don't seem to understand how difficult it is for a striker to play on the flanks and especially on the right wing where he's always coming in on his weak foot. I mentioned the Henry example, Adebayor was the same, Ade wasn't a natural finisher but he got most of his goals from the left side coming in on his right foot. RVP is the reverse. Notice how many tines he's passed up a chance to shoot on his right foot this season? Play him on the left wing and RVP would lose his edge. The side you play on and your preferred foot makes a huge difference. Remember Reyes? He could have been a beast on the wing or as a striker if Wenger had played him on the right instead of the left. He got loads of assists but his goal record wasn't great. These things make a difference.
