Sergio Tejera Rodríguez (born 28 May 1990) is a Spanish professional footballer who plays as a midfielder for Cypriot First Division club APOEL.
Born in Barcelona, Catalonia, Tejera joined local RCD Espanyol's youth ranks in 2000, aged 10.
Six years later, he was spotted by Chelsea scout Frank Arnesen during a match with the Spain under-15s, joining the London club in late March.
In the last days of the 2009 January transfer window, Chelsea agreed to loan Tejera to RCD Mallorca in his country.
On 7 November 2010, he made his first-team – and La Liga – debut, playing 11 minutes in a 3–2 away loss against Real Zaragoza.
