Swansea City says Spanish centre-back Chico Flores has extended his contract with the club until June 2016.

The 26-year-old arrived at the Liberty Stadium from Italian club Genoa for STG2 million ($A2.94 million) last year and has since become a mainstay at the heart of the League Cup winners’ defence.

His previous contract had been due to expire in 2015.

“I’m very happy,” Chico said. “Everything has gone better than I ever expected, considering I only arrived in Wales in the summer. I have found it easier to settle here than when I moved from Spain to Italy.

“The language issue can still be difficult at times, but I’m getting there. My English is improving all the time and I have good communication on the pitch alongside Ash (Ashley Williams), who can also speak a bit of Spanish.

“I had no hesitation in signing a new contract for a number of reasons, but mainly because I can only see the team and the club growing.

“We play good football, which I think suits me, and the warmth of the fans towards me has been unbelievable. To hear them singing my name is amazing, phenomenal. I love them all.

“If you put all that together, everything is perfect, and I hope to stay at Swansea for a long, long time.”
