This week, Gerrard took a 400-mile round trip from Merseyside to England's base in Hertfordshire for confirmation that the groin injury he sustained against Bolton on Saturday was sufficient to rule him out of Wednesday's friendly with Germany.
Capello feels his strategy can erase any room for doubt. And he confirmed conversations had taken place with Benitez and other leading managers to clarify his stance.
"I have no concerns with the clubs," he said. "I have no problem with them. There is a good relationship.
"Some players were injured already but we thought our doctor should check Lampard and Gerrard because they were injured very late in their games on Saturday.
"From now on, the rule will be that our doctor will check the physical condition of the players.
"I spoke privately, not only to Rafael Benitez but other managers as well, but what was said will remain private."
