Juan Mata

Since the opening game of the season against Leicester City, Juan Mata has seen limited playing time. His lack of speed, strength and height have certainly worked against him. With several attacking options, it comes as no surprise that he has been left out.
He can be selected to start on the right wing and offer the much needed creative spark up front. He has good ball control and playmaking abilities. As the game progresses, he can be slotted into that number 10 role to limit his wing play.
Alexis Sanchez

In six matches, the Chilean has only had a handful of chances to score. He has not been up to his full potential since his arrival at Old Trafford. Against an opponent like Derby County, he could break the duck and bring about a much-needed boost to his confidence.
He can play as a left winger or even interchange with the main striker as Lukaku is set to be rested after playing the full 90 minutes everytime since he started the first match of the season.
Anthony Martial

This will be Martial's chance to get on the scoresheet once again as the striker. He has the ability to be ruthless in front of goal. His off-field troubles and transfer talk has got in his way from being the top talent that he is.
He scored against Young Boys and should get more playing time this time around. Things also seem to have cooled down with Mourinho. With Rashford out for at least one more match, Martial's clock is ticking to deliver. Mourinho is likely to have a full bench of his regular starters on standby just in case things don't go according to the script.
