Sorry I know is about Latapy. But on Theobald, I saw him play a few times for Falkirk. I know why Latapy brought him there and also why he lost his way.
Latapy saw the potential of what he could be, Theobald is a decent player who seems to play within himself. He could/should be much more than he is. We know most manager's find him to be a stabilising/calming influence when on the pitch.
Sadly he reverted to current Theobald mode when there. Man took no risks, everything was 'safe - safe' so in the longrun he achieved very little on the pitch that made him standout. No wonder them Falkirk directors was sayin he wasn't progressing as they hoped. Just like on the national side there were other players at Falkirk that were doing what he was and more, so is no surprise he was usually on the bench.
