After impressing on a pre-season trial with the club, Adam Bogdan signed a permanent deal with Bolton as a 19-year-old in 2007, leaving his hometown club Vasas Budapest.
He is widely regarded as a future star of the game and is expected to become Hungary's first choice goalkeeper in the coming years.
Bogdan is a regular in the reserves and recently committed his future to the club by signing a new contract until the summer of 2011.
In September 2009, he joined League 2 side Crewe Alexandra on loan, but was recalled after just one appearance for the club.
