Chelsea are eager to setup a swap deal with AC Milan for Tiemoue Bakayoko.
Milan are considering making Bakayoko's loan deal permanent at the end of the season.
And according to Corriere dello Sport, Chelsea will insist on getting someone in return.
That someone is understood to be Franck Kessie, the Ivorian midfielder.
He is coming towards the end of a two-year loan at AC Milan but the Italian side have an obligation to buy him at the end of the season from Atalanta for around £24m.
But unfortunately for Kessie and Gattuso, they may be forced into selling him straight away this summer in order to comply with Financial Fair Play regulations.
