Ashton, 24, continued his sharp form with both goals in the Hammers' opening-day
Barclays Premier League win over Wigan Athletic last week, only to then limp off with a calf strain.
The injury kept him out of contention for the 2-2 draw against the Czech Republic at Wembley on Wednesday night.
However, with England manager Fabio Capello- who put both Jermain Defoe and then Emile Heskey up front- seemingly
in favour of a lone striker ahead of Manchester United's Wayne Rooney, the Hammers manager sees no reason why that should
not be the former Norwich man.
"If he is going to play with one and wants someone to hold the ball up, bring others into the game and then take
a chance when it is presented, then I do think if a ball drops to Deano in the penalty box, then something is going to happen,"
said Curbishley, who take his men up to Manchester City on Sunday.
"If he is going to play with a lone striker and Rooney coming from deep, flooding the midfield, then perhaps
he will take a look at Dean. Whether that is in the qualifiers, we will have to wait and see."
