Ruben Amorim can spring Manchester United tactical surprise in his first training session today

Ruben Amorim will only truly be able to prepare for his first game in charge of Manchester United later this week when the club's raft of internationals begin to return to Carrington on Wednesday and Thursday.

Amorim will have a couple of likely starters available early in the week, and one of those is Marcus Rashford, whose England exile shows no sign of ending. That is at least good news for his new club boss.

But one key position under the former Sporting coach is the striker. Victor Gyokeres has mastered that role in Lisbon, offering dynamic running that can provide many passing options while exploiting high lines. He has become a goal threat from all around the penalty box.

United don't have a like-for-like to slot in and play the same role as the Sweden international. Joshua Zirkzee is someone who
