Ruben Amorim has admitted that Luke Shaw wants more game time following substitute appearances in his first three games as Manchester United boss.
Shaw, who had been sidelined for 10 months before Amorim's arrival, made his comeback against Ipswich Town and has since come off the bench in wins against Bodo/Glimt and Everton.
The 29-year-old defender is now keen to secure his first starting role since suffering his long-term injury on February 18.
After United's 4-0 victory against Everton on Sunday, Amorim addressed Shaw's ambition to play more as he discussed the time it will take for a settled starting lineup to emerge with his new tactical approach.
"We want always two players [strikers] with different characteristics for changing the game but in the future, we'll have a structure or a base that is more clear in the team," Amorim explained.
"We started this job now and now we have a lot of games. We are changing some details in training. The load is different - I'm not saying better or worse, it's different.
"The way we play is different. Sometimes we have more pressure and we have to make bigger distance running.

"We have a lot of players returning from injury. Kobbie Mainoo was a little risk because he was supposed to play just 60 minutes.
"Noussair [Mazraoui] was clearly in difficulties. Luke Shaw wants to play more but we have to control it.
"So we have to rotate the team but in the future, we will have a different system and you'll see more of a starting XI."
He added: "All the teams have to understand this pressing, what is the type of player who has the ball, what is the best time to press?
"They are smart players so we try to help them but other players have to run. We have to tell them when to start the pressure.
"We try that for every game but you could see that Everton after 15 minutes changed their position.
"[Idrissa] Gueye was running near the line of the centre-backs and it was difficult to cope with and adapt.
"We are trying and the players are believing that in the right moments we can press."
