Chelsea have reached a deal to sign Filipe Luis from Atletico Madrid subject to the defender agreeing personal terms with the Premier League club.
Luis impressed as Atletico won the Spanish title and reached the Champions League final last season and the Brazilian left-back is likely to fill the void left by Ashley Cole's move to Roma.
A statement published on Chelsea's official website read: "Chelsea Football Club can confirm an agreement has been reached with Atletico Madrid for the transfer of Filipe Luis."
The 28-year-old is poised to become Chelsea's second signing from Atletico in the last 24 hours after Spain striker Diego Costa completed his move to Stamford Bridge on Tuesday.
Luis is reported to have cost £20 million after Chelsea agreed to pay the buy-out clause in his contract.
A statement on Atletico's website added: "Atletico Madrid and Chelsea have reached an agreement to transfer the rights of Filipe Luis, pending a medical with the English club.
"The Brazilian player had told our club at the end of the campaign his willingness to join the London side."
Blues boss Jose Mourinho got a close look at Luis when Atletico knocked Chelsea out of the Champions League semi-finals last season.
His dynamic displays convinced Mourinho he was the ideal candidate to solve the left-back dilemma which has troubled him since Cole fell out of favour last season.
With Mourinho believing Cole was no longer playing well enough to start on a regular basis, he was forced to use Cesar Azpilicueta, a right-back by trade, out of position at left-back.
But with Chelsea finishing last season without a trophy, Mourinho is determined to avoid a repeat of that make-shift situation and he moved quickly to tie up a deal for the Brazilian.
Luis joined Atletico from Deportiva La Coruna in 2010 and has made 98 appearances in all competitions for the Madrid side, winning the Europa League in 2012 and the Copa del Rey in 2013 before last season's title triumph.
He has four Brazil caps and was placed on Luiz Felipe Scolari's standby list for the 2014 World Cup.
Believe it or not, Luis Suarez will be a red again next season after Barcelona have unveiled their new crimson away shirt.
Last season, Barcelona played in a garish yellow and red striped away shirt so it may seem coincidental that they have changed to red after purchasing the controversial Uruguayan for £75 million.
Despite the 27-year-old having to serve a four-month football ban for biting Italy defender Giorgio Chiellini at the World Cup, he will be delighted with Barca's new kit seen as though his last two clubs, Ajax and Liverpool, had red home kits.
Suarez is the most expensive signing in the Catalan club's history but he could see his wages reduced to £7 million a year instead of £10 million, if he bites for a fourth time.
Spain striker Diego Costa last night completed his move to Chelsea from Atletico Madrid.
The Brazil-born striker has long been linked with a switch to Stamford Bridge and the clubs agreed a fee early this month, with Chelsea meeting his buy-out clause of £32 million (Dh201.5m).
A statement on chelseafc.com read: “Chelsea Football Club is delighted to announce Diego Costa has today completed his transfer from Atletico Madrid by signing a five-year contract.
“He will join up with the first team for our pre-season European training camp next week.”
Costa joins former Arsenal and Barcelona midfielder Cesc Fabregas in moving from the Primera Division to Stamford Bridge this summer.
His goals helped Atletico claim a first Spanish league title in 18 years last season and he helped the Mad-rid side to the Champions League final, beating Chelsea in the semi-final en route to Lisbon, where Real Madrid won the European Cup.
Costa’s arrival is sure to be a boost to manager Jose Mourinho who effectively blamed his side’s failure to win last season’s Premier League title on his squad’s lack of firepower.
Costa said: “I am very happy to sign for Chelsea. Everybody knows it is a big club in a very competitive league, and I am very excited to get started in England with a fantastic coach and team-mates.
“Having played against Chelsea last season I know the high quality of the squad I am joining. I would like to thank everybody at Atletico who made me into the player I am, it was an incredible time for me, but now I am starting a new adventure and I hope to win many trophies with Chelsea.”
Costa is one of a number of players who featured for Atletico last season who could be plying their trade for the Blues next term.
Belgium goalkeeper Thibaut Courtois spent three years on loan with Los Rojiblancos and is expected to compete with Petr Cech for Chelsea’s number one jersey.
Brazil left-back Felipe Luis is the subject of interest from the Blues, who are seeking a replacement for Ashley Cole after the former England defender’s move to Roma.
Portuguese midfielder Thiago has also been linked with a Stamford Bridge return from Atletico.
