Ruben Amorim has strongly suggested that he will stick with his preferred 3-4-3 system at Manchester United.

The Sporting boss claims that the lack of time on the training pitch makes it a no-brainer to instil what he already knows.

"I know how I am going to play in the beginning, because you have to start with a structure that you know," Amorim explained on Sunday.

"Then you will adapt with the players that you have, some injuries, or no injuries, what kind of players have the abilities to defend, attack, I will discover that in the next few weeks.

"We don't have a lot of time to train, so I have to show something that I know very well. You can take whatever you want from that."
