*WARNING: UNOBTAINABLE* Currently this achievement is unobtainable in the Windows Phone version. In the iOS version, there is a game mode called Enter the Legend where you control one player and earn XP to improve his skills. In this mode, you can earn "Man of the Match" for your player. However, this mode was not ported to the Windows Phone version. There appears to be no other way to obtain "Man of the Match" in any of the included modes. Will update in the future if a patch is released to address this issue, but I wouldn't put any money on it.
