Sir Alex Ferguson has backed Manchester United's "brilliant" medical team after Owen Hargreaves hit out at the treatment he received from them.
Hargreaves, who made an outstanding goalscoring debut for rivals Manchester City on Wednesday night, claimed he felt like a "guinea pig" during four injury-plagued seasons at Old Trafford as he was given several injections which he believes actually hindered his recovery.
But the United manager responded on Friday morning, saying that although he did not know the specifics of Hargreaves' treatment, he had complete faith in the club's doctors.
"We're trying to analyse all the stuff he has said and there will be a statement later to address that," Ferguson said.
