Hello Andrelapse,
Your best bet is to scan Craigs List / Ebay for a replacement playing field. You will have to be patient but sooner or later you should find a parts table that someone is trying to get rid of that has a good playing field. Is there "Tournament Soccer" stamped on the backs of the men? What does the inside of the table look like? I am TS collector / restorer in Wisconsin, I don't have an extra playing field but may be able to help with some of the other parts you may need to help bring it back to original. Shoot me an email and we can discuss further. I have restored the exact same table, a Blue Top Coin Op, and both a 4 Player (Standard) and 2 Player (Mini) Brown Top Coin Op tables.
