Arsenal and Chelsea are set for a transfer battle over Boubacar Kamara, who has impressed at Marseille this season.

The 19-year-old has become a regular first teamer for the French side.

And he has been dubbed the new Thiago Silva.

According to Calciomercato, both London clubs want to sign the player.

Arsenal need defensive reinforcements, while Chelsea boss Maurizio Sarri sees Kamara as someone who could take over from David Luiz next season.

But the Italian outlet also suggests that AC Milan are keen on the player.
