Chelsea will have to pay Barcelona at least £100 million for Philippe Coutinho if they pursue a move for the Brazilian ace this summer.
The Premier League giants currently face a summer of uncertainty given the impeding two-window transfer ban, though the Blues have appealed to the Court of Arbitration for Sport to allow them to sign players for one more transfer window before the ban.
And with the exit of Eden Hazard to Real Madrid appearing imminent, the FA Cup holders are believed to eyeing a move for the former Liverpool man should their appeal to CAS be successful.
However, the Daily Mail claims, the Blues would have to pay at least £100 million for the attacker, who is understood to be pursuing a move away from Camp Nou this window despite signing for the Catalan giants just 18 months ago.
The Brazil international cost the Blaugrana a fee in the region of £145 million, and Barcelona are thought to be keen on recouping as much of that fee as possible if they look to sell Philippe Coutinho at the end of the season.
Meanwhile, Eden Hazard has fears that Chelsea might pull the plug on the £86 million deal and refuse to sell the Belgian superstar in the summer transfer window.
The 28-year-old winger hopes the club will keep their promise and let him join Los Blancos in summer and it was reported in France that €100 million deal is agreed and Real Madrid will announce after the Europa League final.
