Premier League - Hargreaves: United made me their guinea pig
The 30-year-old spent four seasons at Old Trafford, but persistent tendinitis resulted in the player undergoing double knee surgery during the 2008/09 season. Following the operations, Hargreaves played just six minutes of first-team football as he battled to regain fitness and was eventually released by United at the end of last campaign.
He is now enjoying a new lease of life after signing for Manchester City and scored on his debut against Birmingham in the Carling Cup in midweek. However, Hargreaves claims the medical treatment he received at United did more harm than good.
"I received some injections but my tendon was never the same," he is reported as saying in several newspapers. "After the injections, I tried to get back on my feet and they said my tendon was good, but it felt like I was made out of glass. That obviously had a huge impact.
"With my tendon injury, I've had to be a guinea pig for a lot of these treatments. It's difficult. All the people there [at United] are lovely and everybody tries their best, but at times you come to a certain point where you need to make a decision.
"They said it would help. Basically, I was left to pick up the pieces, which was incredibly frustrating. I wanted to play. Everyone wanted me to play, so it's not really an option to say, 'sit it out and rest for six months'. With hindsight it's a lot easier, but I wish I had not had the injections."
