The Blaugrana are desperate to sign a centre-back this summer, and following Thiago Silva’s contract extension at Paris Saint-Germain, have turned their attentions to the Premier League.
According to Mundo Deportivo, the Camp Nou hierarchy are currently in negotiations with the English teams for the defensive duo.
Luiz has been a long-term target for Gerardo Martino’s men, and could cost in the region of €40m.
Agger meanwhile, is seen as Plan B for the Catalan club, and could cost €25m.
Denis Cheryshev has thanked Real Madrid for his new contract and made himself available to ‘accept any decision of the club’.
The Russian Under-21 international, who recently penned a contract extension through to June 2017, continued his run in preseason with the senior squad by appearing in their 3-1 win overnight against LA Galaxy.
“I am grateful to the club for the opportunity that they have provided me. I have spent a lifetime fighting for this and I am very happy,” enthused Cheryshev post-match.
“I will accept any decision of the club and will abide with pleasure by the coach for any decision made about my future.
“I am not thinking about my future, now I am enjoying this tour. I am happy and will fight to the end to stay here.
“The coach is giving many opportunities to the younger players, this is a great step taken by the club. The cantera is full of worthy players.”
Barcelona have reportedly made clear this week that forward Alexis Sanchez is ‘untransferable’ this summer.
The Chilean had been linked with a return to Serie A earlier this summer with Juventus and Inter said to be pressing, and recent reports now link Napoli with interest.
However, Vice-President Jose Maria Bartomeu is quoted by Chilean newspaper El Mercurio as listing the 24-year-old as ‘untransferable’ this summer.
Alexis has struggled for consistent bursts of form and fitness in his two years so far at Camp Nou and faces increased competition for places this term from Neymar.
The player, though, is reported as intent on staying with the Catalans, and intimated as much earlier this week to reporters.
