Chelsea have reportedly stepped up their interest in Marseille centre-back Boubacar Kamara by sending scouts to watch him in action, according to Mercato365, relayed by Sport Witness.
The report claims that Blues scouts watched Kamara in the 3-0 defeat to Lyon on Sunday.
The 19-year-old has featured heavily for Marseille this season under Rudi Garcia, making 35 appearances in all competitions.
His consistent displays have caught the eye of Chelsea, who have been monitoring the teenager in recent months.
Kamara has been regarded as a future star by Marseille officials, however, securing a potential deal may prove difficult for Chelsea.
The club had their transfer ban appeal turned down by FIFA last week, however, Chelsea look set to take that appeal to the Court of Arbitration for Sport.
If the appeal is successful, Chelsea may see their ban frozen over the summer, which could allow the club to land Kamara over the summer.
Five defenders Chelsea could hand first-team opportunities to next season
Zouma has impressed on loan at Everton this season and could find himself around the Blues first-team during the next campaign.
Capable of playing at the back or as a defensive midfielder, Sarri could look to hand Ampadu more regular first-team opportunities next season.
Versatile defender James has caught the eye in the Championship with Wigan this season and would provide Sarri with an option anywhere across the back line.
Tomori has impressed at Frank Lampard’s Derby County this season and is another option for the Italian.
Aina is believed to have impressed Sarri while on loan at Torino this season and could end up staying at Stamford Bridge over the summer, despite being linked with a permanent move away.
