Roberto's future at Barcelona is reportedly uncertain following Ernesto Valverde's arrival at the Nou Camp.

The 25-year-old impressed under Luis Enrique last year as he established himself in the heart of Barcelona's midfield.

But Barcelona are getting ready for a summer upheaval following Neymar's £200m to Paris St-Germain.

The likes of Paulinho, Philippe Coutinho and Eden Hazard among others have been linked with a move to Barcelona in recent weeks as they look to reinvest heavily.

Any midfield arrivals could force Roberto down the pecking order at Barcelona but he certainly isn't short of options.

The Spain international has a £36m release clause in his contract at the Catalan club and according to Spanish publication Don Balon Chelsea, United and Monaco are all considering making a bid.

Antonio Conte has recently aired his frustrations over Chelsea's lack of activity in the transfer market.

Despite signing Tiemoue Bakayoko, Alvaro Morata, Antonio Rudiger and Willy Caballero the Chelsea boss believes his squad isn't big enough for the season ahead and wants four more signings.

Jose Mourinho meanwhile has already added Nemanja Matic for £40m to his midfield options but like his fellow Premier League boss is also on the lookout for more recruits.
