Former Arsenal defender Martin Keown agrees that Chelsea have done phenomenal transfer business.
Chelsea FC was able to sign spanish stalwarts Diego Costa, Cesc Fabregas and Filipe Luis and strengthened almost all areas of their gameplay, truly creating an almost invincible side.
Chelsea were also able to sell David Luiz for a huge £50m to Paris Saint Germain while gaining a healthy profit of £28m by selling Romelu Lukaku, who joined Everton.
“Chelsea won it the day they sold David Luiz for £50m. And then they got £28m for Romelu Lukaku. Unbelievable business. Financial fair play rules have made them become better negotiators,” he told the Daily Mail. (Retrieved from OFF THE POST)
