Liverpool legend Jamie Carragher slammed Manchester United's performance for the 1-1 draw at West Ham United. United were second best for much of the game.
"I would make a change and bring Wilson on. I am looking at the lack of movement compared to Sakho and Valencia," said Carra.
"I am not saying these players (Falcao and Van Persie) are bad players, but it is not a partnership.
"I think they are too similar. They are standing still. There is no energy. They have spoken at times about United's slow play.
"Now, is it down to the passing or is it down to the lack of movement? That is what they have got to change - they have been world-class strikers but as a partnership it is not working.
"When you are almost 30, as those two are, you need a young fella (like Wilson) running around you."
