Sunderland midfielder Jack Rodwell has shed light on his desperate attempts to overcome his constant struggles with a hamstring injury.

The 24-year-old has revealed that he was the subject of 50 injections in the space of five days by controversial specialist Dr Hans Muller-Wolfhart in an attempt to get over his hamstring problems.

"I flew to see him in Munich. I was there from Monday to Friday morning and had about 50 injections over that time. He injects and injects," explained Rodwell.

"There's a lot of anti-inflammatories and lubricants for the joints – it's all technical stuff, the physios know more than me.

"I just go along with it, and I'll do anything to stay fit. There's nothing major, it's just niggling injuries, but I don't want it to continue. When you' re out for a week here and there, it sets you back and you're out of the team."
