Despite it being a smaller squad to work with this week, Ten Hag has put his ideas across and Rashford can already see it having an impact.
"We have got that feeling of excitement and that buzz around the training ground again and so it is definitely positive going into pre-season," he told MUTV.
"It is just about, one, getting the principles right of how Erik wants us to play and the details, and, two, enjoying it. In the first week of training we have done both and everyone is looking forward to going on the tour and putting what we have done in training into the first games.
"I think for me, it is just fresh ideas, fresh tactics and a new personality that has been added to the team. I am looking forward to working with him but also for us to give ourselves time as well to fit into what he wants us to do and to really feel natural doing it.
"That is what he wants us to do, for it to be second nature doing the things he wants us to do. Those things do take time but it is a challenge we are all looking forward to."
