Chelsea boss Thomas Tuchel has refused to comment on whether he will push to sign more defenders in the final days of the summer transfer window amid strong interest in Leicester City's Wesley Fofana.
The 21-year-old was left out of Leicester's squad for the game against Southampton, which Brendan Rodgers' side lost 2-1 at the King Power Stadium, after he agreed personal terms with Chelsea on a six-year deal, according to transfer expert Fabrizio Romano.
After reportedly seeing two bids turned down by Leicester, Chelsea have not yet made a third approach and Tuchel has refused to comment on whether he will make another attempt.
After summer arrival Kalidou Koulibaly picked up a red card in the defeat at Leeds United, signing another centre-back could be a priority for Chelsea before the weekend.
