Hakim Ziyech has been linked with a move away from Chelsea this summer, but the Moroccan international is disappointed at how things are going.
Chelsea have loaned out club-record signing Romelu Lukaku back to Inter and have confirmed a £20m exit for Timo Werner, who returned to RB Leipzig.
Reports have it that Ziyech remains frustrated at Chelsea, as his transfer has stalled, with the Blues continuing to weigh up a move for Pierre Emerick Aubameyang.
Ziyech has been keen to join AC Milan all summer, but Chelsea are also not keen on permitting a deal until the Blues have a replacement.
According to reports, the Moroccan has grown frustrated at the slow speed of AC Milan to sign him on loan with an option to buy and has instructed his lawyer to find alternative options.
Tuchel is aware of the dissatisfaction of the 29-year-old winger, but is open to keeping the Moroccan star for another season, if need be.
Ziyech was an unused substitute in the 1-0 victory against Everton.
