I believe Amorim knows how to make substitute on where there's laxity or weaknesses on the pitch. I could remember during Liverpool match, after Liverpool equalized the goal, Amorim immediately brought out Mainoo and put in Gnarcho to strengthen the attack force, and it worked. I don't have much doubt on Amorim capabilities because I know he has the potentials in him.
Amorim does have good potential in coaching a team and now he will continue to try new things at Manchester United including in terms of player rotation and also in terms of bringing some new players into the team and selling some old players to other teams. In addition, Amorim is also aware that Manchester United will find it quite difficult to reach the best position in their domestic league this season so that most of his focus must be directed to the Europa League this season so that Manchester United can be a candidate for champions in this competition.
