In 1990, he moved to Baník Ostrava, where he did not manage to get a place in the senior team, even though he did sign a contract when he turned 18.

There he had no real concurrence and put up good performances, which drew the attention of Slovan Liberec that purchased him in 2004.

He was first considered a substitute (behind Zbyněk Hauzr), but quickly became number one and even one of the best goalkeepers in the Czech league, spending 740 minutes without conceding a goal in 2006.

On 15 November 2006, he made his debut for the Czech national team in a friendly against Denmark that ended up in a 1–1 draw.

In August 2014, Čech was signed by Delhi Dynamos in the newly formed Indian Super League.
