Signed by Spurs in the transfer window of January 2005 to add experienced back-up for Paul Robinson in the goalkeeping department.
An experienced performer at Slavia Prague, Cerny is a tall keeper with Champions League experience and 3 full and 11 Under-21 international caps to his name.
Came on to make his first appearance against Aston Villa in May 2005, when Robinson left the field injured and played the remaining games of that season. Has been given the opportunity to show his ability in League and FA Cup games, but also filled in when Robinson was absent injured in the early part of 2007, showing he was a capable keeper and although he conceded a few goals (two against SC Braga at home in the UEFA Cup and three against Chelsea in the FA Cup Sixth Round tie at Stamford Bridge), he didn't have much chance with any of them.
Gained first team run in 2007-08 when Paul Robinson was dropped and did well, until he dropped a cross in the UEFA Cup away leg against Slavia Prague and then was left out of the return leg and missed the League Cup Final, although gained a medal for the win as he was among the unused substitutes.
Has been a model professional in providing experienced back-up for Tottenham and would have been a first choice at many other clubs. This was proved when his loan came to an end on 20th May 2008 and he was immediately signed by Queens Park Rangers.
