Career
Fernandez joined Bayer Leverkusen"s youth academy in 2000 and started playing for the club"s reserve team in 2005. In 2006, he signed a professional contract with the club to play understudy to Hans-Jörg Butt and René Adler. He made his Bundesliga debut on 10 February 2007 against Eintracht Frankfurt, coming on as a substitute following a red card to Hans-Jörg Butt.
He made one more appearance in the Bundesliga that season before being replaced by René Adler, who went on to establish himself as the club"s first-choice goalkeeper.
Following the departure of Hans-Jörg Butt in the summer of 2007, Fernandez became the second-choice goalkeeper in Leverkusen"s first team, also continuing to occasionally play for the reserves. Due to another injury to Adler, Leverkusen started their 2008-2009 Bundesliga campaign with Fernandez in goal, with him subsequently making further three Bundesliga appearances before Adler returned to action in mid-September 2008.
At the end of the 2010-2011 season, he left Bayer Leverkusen. After a year without a club, he signed for 1.
Football Club Saarbrücken in 2012.
