Wondolowski likens Altidore to Ronaldo
United States striker Chris Wondolowski has likened replacing team-mate Jozy Altidore to filling in for Portugal's Cristiano Ronaldo.
Jurgen Klinsmann's men face Portugal in Manaus on Sunday knowing that a win will see them qualify for the last 16, providing that Ghana drop points against Germany on Saturday.
However, the USA will be without Sunderland forward Altidore due to a strained hamstring suffered in the 2-1 win over Ghana on Monday.
It remains to be seen who will take the place of Altidore should he be unable to play, although a pairing of Wondolowski and AZ's Aron Johannsson has been mooted.
But for San Jose Earthquakes star Wondolowski, the prospect of coming in for Altidore is a daunting one.
He explained: "Jozy is a special player – that's like saying 'Hey, go be Cristiano Ronaldo'.
"You can't necessarily replace certain aspects of it, but I think that both Aron and I bring different styles, different sets of skills that I think are useful.
"And I think that's what we have to go do is incorporate those skill sets, and fit into the game plan as well.
