Ralf Rangnick will discard his favoured formation in a bid to reverse Manchester United 's poor form and get Jadon Sancho firing.
The interim manager is ready to do away with his 4-2-2-2 set-up and pursue a 4-3-3 system he hopes will benefit United's stuttering £73million winger.
The Red Devils drew 2-2 with Aston Villa on Saturday to leave them seventh in the table with a poor record of one win in four Premier League games.
Sancho had to settle for a late cameo against Steven Gerrard's side and the struggling England international has only scored twice since his big-money arrival from Borussia Dortmund last summer.
Rangnick admits his traditional 4-2-2-2 has not played to the 21-year-old's strengths and the German is ready to shake up his tactics so he can line up in his "best position".

"We have now decided to play a 4-3-3 like we did against Aston Villa, with one holding six, two eights and three offensive players," Rangnick said ahead of United's trip to Brentford on Wednesday night.
"It's clear in a 4-3-3 that he (Sancho) is a player for either of the wing positions, either left or right, he can play both.
"I think he would prefer a little bit the left side, because then he can switch inside and shoot on goal with his strong right foot.
"But for me there's no questions about his position.
"He's a winger, as we say in Germany, someone who can dribble fast with the ball and for me there's not at all a question over the best possible position for him.
"But again, it's not only about training at the highest possible level.
"I said that to him by the way the day before yesterday - confirm the performances you show in training when you're playing on the pitch."
A shift to a formation which uses natural wingers is sure to suit Sancho more than the 4-2-2-2 system which had him playing as an attacking midfielder.
The former Manchester City academy star excelled on either flank throughout his time with Dortmund and Rangnick is sure he can replicate those performances if he overcomes his mental block.
But the interim boss emphasised the formation he uses is merely a "means to an end" rather than a way of guaranteeing an upturn in results.
"Of course, in my opinion, this formation has to fit to the players you have available," Rangnick added. "In the long term, it would be good to have one formation or one style of play."
