Barcelona expect Premier League clubs to test their resolve over Philippe Coutinho with Chelsea monitoring his situation.
As the Blues prepare for life after Eden Hazard, they are keeping tabs on the £142m ex-Liverpool playmaker at the Nou Camp.
The 26-year-old is considering ending his Barcelona nightmare and Chelsea would be able to afford a move at the end of the season.
They are interested in bringing back Coutinho – a proven Premier League star – according to The Independent.
His future is up in the air, despite Barcelona’s public decree he is not for sale, and Liverpool are not expected to challenge Chelsea over a move.
Isco and Mateo Kovacic could both join Chelsea on a permanent basis from Real Madrid this summer with Hazard going the other way.
Starsport understands the player wants to go and will have just 12 months left on his deal this summer, so Chelsea are already eyeing up replacements.
And one potential scenario could see them land Hazard’s successor in an exchange with Real.
The Sun suggest Hazard’s arrival could spell the end of Isco’s spell in Madrid, and could be sent to Chelsea in a player-plus-cash deal.
Real are also likely to allow midfielder Kovacic to make his Stamford Bridge loan permanent too.
Chelsea had an offer for Nicolo Barella accepted in January before a move collapsed, according to Italian outlet TuttoMercatoWeb.
The 21-year-old, who has shone in La Liga with Cagliari, could have secured a move to Stamford Bridge last month had he not rejected the switch.
Cagliari accepted an offer of €50m (£44m) for Barella’s services before he snubbed the Blues.
It is believed the young star wanted to stay in Italy for family reasons.
Barella was targeted, along with PSG signing Leandro Paredes, last month to succeed Cesc Fabregas as Chelsea’s creative midfielder for the future.
But they ultimately signed just striker Gonzalo Higuain on loan from Juventus and winger Christian Pulisic from Borussia Dortmund, who will team up with the Blues come June.
