Chelsea interim boss Frank Lampard has confirmed that Kalidou Koulibaly will continue to be unavailable for selection ahead of Tuesday's trip to Arsenal, and could in fact miss the remainder of the season.
The defender has been out injured since picking up a hamstring problem in the Champions League quarter-final first-leg defeat to Real Madrid. Koulibaly has missed the last three games, with the Blues conceding six goals and losing three.
There was little hope that the Senegal international could return for the trip to the Emirates Stadium, but Lampard has confirmed he will remain out for the foreseeable future. "Yeah, [he's] out for a while still," Lampard said. "I think it will be a tight call for the season, he's working away.
