Cattermole in pledge to Cats fans

The combative midfielder joined the Black Cats last summer from Wigan but suffered a serious knee injury against Liverpool in October and has subsequently been affected by a series of niggles. Cattermole told the official club website: "It's been a frustrating season but I have learned a lot about myself and about my body. "To be honest it's been totally different to what I'm used to. I just want to get this season out of the way because my form has been disappointing this year and I put that down to injuries. "I'd go out to training thinking I was made of glass. I have never been injured in my career but hopefully it's all behind me now. "I know I can be successful here. Hopefully I can get a good pre-season under my belt - I think I can show how good I really am."
