Edwin van der Sar hints AC Milan striker Klaas-Jan Huntelaar could be a hit at Manchester United.
United are again being linked with the Dutchman this week.
"I played with Klaas for two or three years with the national team and he's a great goalscorer," Van der Sar said. "He's a guy who can hold the ball up well, like we saw in Milan's game against Udinese on Friday.
"When he gets a chance, he can finish it and you always have to pay attention to him when you're up against him.
"He had a hard time at Madrid and he hasn't started a lot of games for Milan, but he can still be a great player."
