Chelsea are reportedly closing on a deal to sign Porto defender Alvaro Pereira.
The versatile Uruguayan international has been heavily linked with a move to England this summer, with Liverpool boss Kenny Dalglish thought to be keen on the 25-year-old.
However, reports in Portugal claim Chelsea are now favourites to land the full-back, who helped his country win the Copa America earlier in the summer.
Recently appointed Chelsea boss Andre Villas-Boas, who managed the player at the Estádio do Dragão last season, is thought to be key to any possible deal to that would see the player move to Stamford Bridge.
Player agent Alejandro Savich confirmed that a handful of clubs have made contact with the Primeira Division champions over a move, although a deal is far from done.
"Since the end of last season several clubs have asked about the player but it depends on the club," said Savich.
A major stumbling block for Chelsea is the £25 million transfer fee, according to talkSPORT, with the Blues likely to try and negotiate a cheaper deal.
With Villas-Boas eager to replace the versatile Yuri Zhirkov in West London following his departure from Chesea in the week, Pereira would appear to fit the bill given his relationship with the 33-year-old manager.
