My prediction - Rom will start against Newcastle with Rashford rested due to groin strain, he'll score a brace or a hat-trick which will put him in contention after the International break, and over the coming games we'll slowly remember that Rashford isn't a natural finisher and often blows big chances as a CF, while Rom (in form) will bury a chance (see yesterday) and he will slowly wrestle the CF position back off Rashford...
Rashford will go back to being played as a right forward and will rotate with Lingard, and we'll settle with a front 3 of more or less...
Rashford/Lingard----Rom----Martial/Sanchez
In short - Rom will get back into the starting 11 as the main CF, we'll all hail Ole for resurrecting his form and he'll end the season as one of the in form PL strikers along with Kane and Aguero (as he does pretty much every season).
