Although Man Utd are still interested in Van Nistelrooij, he won't be back in action until March next year, and will probably finish the season with PSV.
So that means Man Utd have renewed their interest in Gabriel Batistuta.
He's old, he'll play 1 or 2 seasons with them, then Van Nistelrooij comes in. If Salas came, he would only be resented to the bench. He should go to Arsenal instead. Bergkamp will leave at the end of next season, and Suker is leaving at the end of this season.
