USA manager Juergen Klinsmann insists he is staying abreast of all players who are jostling for a World Cup position.
Following the January camps in California and Sao Paulo, Klinsmann suggests that there are plenty of positions up for grabs as he ponders who he will take to Brazil this summer.
A number of World Cup hopefuls such as defensive pair Oguchi Onyewu (who recently joined Sheffield Wednesday) and Tim Ream (Bolton), midfield couple Danny Williams (Reading) and Brek Shea (Barnsley on loan from Stoke City), and injured German-based duo Steve Cherundolo (Hannover) and John Anthony Brooks (Hertha Berlin), are all being looked at by Klinsmann and his coaching staff.
"We just want them to be on the field and build their case," he said.
"We communicate with them, players like Oguchi Onyewu, Tim Ream, and Danny Williams. You have Brek Shea, who went down into the Championship from Stoke to play games and is now playing 90 minutes almost every week.
"You have Timmy Chandler at Nurnberg, who for six months has been doing a very consistent, good job. Jermaine Jones goes to Besiktas (from Schalke) and will pick up the rhythm of playing games again.
"We follow the players that have injury problems like Steve Cherundolo, who is still having issues, and John Anthony Brooks with Hertha Berlin who is hopefully back next week.
"Same with (Hoffenheim's) Fabian Johnson who broke his arm and is hopefully back next week as well. Being in February and a few months prior to the World Cup, you want to see them all play.
"You have to give them a clear message that only if you pick up a rhythm and play week-in, week-out, will you complete one of the big keys in order to make the World Cup roster.
"That's why we are really happy some of them now are starting to get their rhythm. This all plays a vital role in evaluating them, and then we have to make the vital calls in May."
