Cristiano Ronaldo's last chance of leaving Manchester United this summer is with Borussia Dortmund

Ronaldo is being put to run "punishment" laps in training for the poor start to the season

Cristiano Ronaldo's last chance of a Manchester United exit is via a transfer to Borussia Dortmund. His agent Jorge Mendes is actively working on a move.

Ronaldo is still intent on leaving Old Trafford this summer in order to play Champions League football. Although Manchester United continue to state the 37-year-old is not for sale, that stance is yet to be tested by a concrete offer. But sources at Old Trafford tell CBS Sports there is a growing feeling, at least within the football department, that allowing Ronaldo to leave is the best approach.

Joel Glazer is the most vocal roadblock to an exit since he'd ideally like to keep Ronaldo and has repeatedly emphasized his commercial worth during internal discussions. But new manager Erik ten Hag would now prefer to let him go should an acceptable offer arrive.
