Swansea chairman Huw Jenkins says the club are stepping up their preparations for their maiden Barclays Premier League campaign after defender Angel Rangel committed his future to the Liberty Stadium outfit.
The Swans had already seen midfielder Darren Pratley and goalkeeper Dorus de Vries leave the club after failing to agree new deals, and there had been fears that full-back Rangel would follow suit.
But the 28-year-old Spaniard has agreed a new three-year deal in south Wales and Jenkins said: "We are very happy to secure Angel's future for the next three years. He has played a big role in the club's success since he arrived here, and we were very keen for him to be part of our plans going into the Premier League."
He added: "Over the last few years there has been interest from Premier League clubs in Angel, but he is very pleased to have achieved his dream of reaching the Premier League with the club he left his native Spain for."
Jenkins believes that extending Rangel's four-year stay, and the signing of Danny Graham for a club-record £3.5million fee, stands the club in good stead as manager Brendan Rodgers looks to further strengthen his play-off-winning squad.
"We are on top of every situation we are involved in," Jenkins told the club website.
"We will go about our business with the best interests of our football club in mind.
"The uncertainty of whether you will win promotion or not sometimes causes some difficulty in pursuing new players.
"But I'd like to let our loyal supporters know that we are working very hard at the club in order to bring the right players to Swansea City.
"We have also broken our club transfer record to sign Danny Graham, and are working towards adding further quality to this squad."
