Chelsea winger Christian Pulisic has admitted that there is every possibility that he could leave the blues in the January transfer window. The American International has been starved of first-team opportunities at Stamford Bridge. Yet, he has insisted to stay at the club in the hope that the situation would improve after the change of management, which took place earlier in the season after the arrival of Graham Potter in place of Thomas Tuchel. Even under the new management, however, Pulisic has been unable to get a lot of action and he has been used very sparingly.
