Sir Alex Ferguson unhappy with England U21 manager Stuart Pearce for disclosing nature of Phil Jones's injury
After Jones withdrew from the Under-21 friendly with Sweden on Tuesday, Pearce claimed the former Blackburn man was suffering from shingles.
"What about doctor confidentiality?" said Ferguson. "We are disappointed with that."
"It is something we have to address," said Ferguson. "The FA is a big organisation, things can leak from a lot of different places.
"But that was a conversation between our doctor and theirs, and shouldn't have gone any further."
