Having scored four goals in five games prior to the weekend, Zamora had been mentioned as a possible surprise inclusion for the squad to face Egypt at Wembley, with club manager Roy Hodgson and a variety of team-mates lining up to emphasise the striker's international credentials in recent weeks.
Fabio Capello ignored the claims of the striker though, instead picking a trio of target men in Carlton Cole, Peter Crouch and Emile Heskey to complement the talents of Jermain Defoe and star striker Wayne Rooney.
Kelly believes Zamora merited a chance at international level following his impressive form with Fulham, but with the World Cup just 100 days away, it seems the striker may be fighting a losing battle.
"He has been on such good form for us, scoring a lot of goals," Kelly told Soccernet. "Bobby has always been the sort of player that will hold the ball up.
"But now this season we needed a striker that will score goals. Bobby has added that to his game as well and that has really opened up a lot of people's eyes.
"It probably was a bit of a surprise with his current form that he hasn't been given a chance but all he can do is keep performing the way he is and hopefully push himself into the squad for the World Cup. There isn't much more he can do than perform the way he is."
Zamora has scored 15 goals for Fulham in all competitions this season - a figure which represents his best individual tally since the 2001-02 campaign with Brighton in League One.
