Well MUSC says this player did these things across more than one club. Fine.
The player is still playing down in the Championship. Fine.
Put those two things together and it's tricky. Kuszczak was my first thought on "players who played for at least one top team, probably didn't win or play much and are now in a division below".
On that note, Manuel Almunia could be another having recently played for Watford but he only played for Arsenal upstairs. Ex-Tottenham Gomes (another goalkeeper, eh?) is also down in the Championship but I don't recall him finishing 2nd in the Premiership or losing all those cup finals.
