Ten Hag will be hopeful that this time around against the Blues that there are no red cards to contend with.
In a matchday Q&A he was asked about that fixture and his experience of Stamford Bridge. He responded: "I hope we don't experience playing with 12. If we play with 11, I think we have a good chance to win".
Should United win they will extend their impressive five-game unbeaten streak, and in the process end Chelsea's unbeaten start under Potter.
