Barkley’s future at Goodison Park is far from clear and Ronald Koeman has urged the England midfielder to make a swift decision on whether he will stay or not.
The 23-year-old will enter the final 12 months of his contract at the end of the season and is being heavily linked with a summer move.
Manchester United boss Jose Mourinho is reportedly keen to bring Barkley to Old Trafford, while north London rivals Arsenal and Tottenham are also monitoring his situation.
According to the Daily Express, Chelsea are the latest club to express an interest in the dynamic midfielder, with Antonio Conte impressed by the player’s potential.
It is claimed Barkley may be seen as an ideal replacement for Cesc Fabregas, who continues to be linked with a move away from Stamford Bridge.
Meanwhile, Chelsea’s Brazilian attacker Willian has responded to speculation he could join United during the summer transfer window.
